Statistics in Monitoring the Nation’s Health<br />
Nathaniel<br />
Schenker<br />
This month, I have invited Nathaniel Schenker of the National Center for Health Statistics to discuss how that<br />
agency provides information about the nation’s health. Since before 1960, NCHS has monitored health statistics,<br />
initially under the stewardship of Forrest Linder. It is a wonderful resource for data and information.<br />
2 AMSTAT NEWS SEPTEMBER 2008<br />
I’ve spent the past nine years at the<br />
National Center for Health<br />
Statistics (NCHS), having previously<br />
taught biostatistics at UCLA for<br />
11 years and worked at the U.S.<br />
Census Bureau for three years before<br />
that. NCHS, which is part of the<br />
Centers for Disease Control and<br />
Prevention, is the nation’s principal<br />
health statistics agency. Its motto is<br />
“Monitoring the Nation’s Health,”<br />
and its mission is to provide statistical<br />
information that will guide actions<br />
and policies to improve the health of<br />
the <strong>American</strong> people.<br />
What Is Done at NCHS?<br />
When I used to take my infant son<br />
for a medical check-up, the pediatrician<br />
would plot his height and<br />
weight on growth charts. Little did<br />
I know the charts were produced by<br />
NCHS and were based primarily on<br />
data from NCHS’ National Health<br />
and Nutrition Examination Survey<br />
(NHANES). Similarly, when cars<br />
began to use unleaded gasoline, I<br />
didn’t realize the formulation of policy<br />
to move away from leaded fuel was<br />
based on analyses of data on bloodlead<br />
levels from the NHANES. (For<br />
more on this policy, see the President’s<br />
Invited Column in the May issue of<br />
<strong>Amstat</strong> <strong>News</strong>).<br />
Indeed, NCHS collects and analyzes<br />
data and produces information<br />
for the public on a wide range of<br />
health topics, including vital events<br />
and demography, health conditions<br />
and behaviors, access to and quality<br />
of health care, and injuries and<br />
disabilities. Sources of NCHS data<br />
include birth and death certificates,<br />
as well as various sample surveys that<br />
collect information via review of<br />
medical records, personal interviews,<br />
physical and dental examinations,<br />
and laboratory tests.<br />
‘S’ Stands for ‘Statistics’<br />
Given that the “s” in NCHS stands for<br />
“statistics,” statisticians obviously have<br />
a major role in the work of the agency.<br />
As do many agencies in the federal<br />
statistical system, NCHS has separate<br />
divisions that focus on specific data collection<br />
systems and topics. Statisticians<br />
within these divisions work on the<br />
design and implementation of the<br />
data collections, analyses of the data,<br />
and preparation of the data for release<br />
to the public. Other statisticians (such<br />
as I) work in offices within the agency<br />
that focus more on cross-cutting analyses<br />
and research and on the development<br />
of statistical methodology, while<br />
also providing consultation to the data<br />
divisions. Examples of methodological<br />
research areas at NCHS include<br />
optimal strategies for sample design,<br />
questionnaire design, modeling and<br />
estimation, data mining, developing<br />
indexes of health, confidentiality, and<br />
handling missing data.<br />
Nathaniel Schenker, Senior Scientist for<br />
Research and Methodology, NCHS/CDC<br />
An NCHS statistician often works<br />
as part of a team, together with other<br />
statisticians as well as specialists<br />
in areas such as computer science,<br />
demography, economics, epidemiology,<br />
medicine, public health, and<br />
sociology. There are ample opportunities<br />
for individual research projects,<br />
as well. Moreover, collaborations frequently<br />
occur with researchers at other<br />
federal and local government agencies,<br />
in industry, and in academia.<br />
Mr. Academic Goes (Back) to<br />
Washington<br />
When I decided to leave my tenured<br />
academic job in UCLA's Department<br />
of Biostatistics in sunny California to<br />
return to the East Coast and work for<br />
the government, I was often asked,<br />
“Are you crazy? Why would you do<br />
that?” Well, there were a number of<br />
reasons, some of them personal, such<br />
as my growing up in Washington and<br />
the East Coast having a lot to offer.<br />
As a statistician, however, I was excited<br />
by the prospect of working at the<br />
source of health data that are important<br />
and of interest to many outside<br />
the agency. Indeed, at UCLA, I often<br />
ran across NCHS data and researchers<br />
analyzing them. Also, NCHS seemed<br />
like a relatively small, friendly agency,<br />
so I didn’t feel as though I’d get lost<br />
working there. And, it seemed to have<br />
a culture of conducting research, so<br />
I thought I’d be able to continue my
esearch career. (After coming to NCHS,<br />
I also became an adjunct professor in the<br />
Joint Program in Survey Methodology at<br />
the University of Maryland, so I didn’t have<br />
to abandon academia completely.) Finally,<br />
the Washington area has an exceptionally<br />
active statistical community. For example,<br />
it is home to the largest chapter of the ASA:<br />
the Washington <strong>Statistical</strong> Society.<br />
Do I miss being a full-time professor at a<br />
fine university? Yes. Am I glad that I changed<br />
jobs? Absolutely. Besides the fact that<br />
changing jobs every once in a while helps to<br />
'keep one’s blood flowing,' I’ve enjoyed the<br />
atmosphere and work at NCHS. I’m less of<br />
a free agent in some ways now than I was<br />
in academia (although I also don’t have to<br />
hustle for grant support the way I did), and<br />
there are some bureaucratic hassles involved<br />
in working for the government; but every<br />
job has its own administrative headaches,<br />
and any annoyances due to governmental<br />
red tape have been far outweighed by the<br />
opportunities I’ve had for interesting work.<br />
A Small Sample of My Projects<br />
To illustrate some of the statistical work<br />
that goes on at NCHS, I’ll briefly outline<br />
a couple of major projects in which I’ve<br />
been involved.<br />
In 1997, the Office of Management<br />
and Budget revised the standards for classifying<br />
federal data on race and ethnicity.<br />
A key provision was that respondents to<br />
federal data collections be given the option<br />
of choosing more than one race group to<br />
describe the person in question. Because the<br />
previous (1977) standards called for only a<br />
single race group to be reported, data collected<br />
under the 1977 standards are not<br />
comparable with data collected under the<br />
revised standards. This can cause problems<br />
in trend analysis, the calculation of a vital<br />
rate—for which the number of events in<br />
the numerator and the population size in<br />
the denominator can come from different<br />
sources using different standards—and in<br />
other types of studies that combine data<br />
classified under the two standards.<br />
The decennial census, a widely used<br />
source of denominators for vital rates, began<br />
allowing multiple-race reporting in 2000. To<br />
make the 2000 census data (and intercensal<br />
and postcensal estimates) comparable<br />
with data classified according to the 1977<br />
standards, NCHS, with assistance from the<br />
U.S. Census Bureau, produced “bridged”<br />
census counts by county, age, sex, and<br />
race—estimates of the counts that would<br />
have been obtained had the prior standards<br />
been in effect (www.cdc.gov/nchs/about/<br />
major/dvs/popbridge/popbridge.htm). The<br />
bridging process used models predicting<br />
responses under the prior standards from<br />
responses under the current standards and<br />
covariates. These bridging models were<br />
developed using data from NCHS’ National<br />
Health Interview Survey (NHIS), which has<br />
allowed multiple-race responses for many<br />
years, but which also asks multiple-race<br />
reporters for a single race group that best<br />
describes the person in question.<br />
I worked on many aspects of this project,<br />
but perhaps my biggest contributions were<br />
to the formulation of the overall approach<br />
used to solve the problem, the development<br />
of the bridging models, and the derivation<br />
of methods for assessing uncertainty in analyses<br />
that use the bridged data.<br />
A second project involved multiple<br />
imputation of missing income data. The<br />
NHIS provides a rich source of data for<br />
studying relationships between income<br />
and health and for monitoring health<br />
and health care for persons at different<br />
income levels. However, the nonresponse<br />
rates are high (roughly 30%) for two key<br />
items: total family income in the previous<br />
calendar year and personal earnings from<br />
employment in the previous calendar year.<br />
To handle this missing-data problem and<br />
allow analysts of the data to assess the<br />
uncertainty due to missing data, multiple<br />
imputation of these items has been<br />
performed for several years (www.cdc.gov/<br />
nchs/about/major/nhis/2006imputedincome.<br />
htm) in collaboration with researchers at<br />
the University of Michigan.<br />
Several features of the data made the<br />
project particularly challenging and interesting.<br />
First, the data are hierarchical<br />
in nature, with one of the key variables<br />
reported at the family level and the other<br />
reported at the person level. Second, there<br />
were cases in which the value of one variable<br />
(e.g., personal earnings) could be<br />
restricted by the value of another variable<br />
(e.g., whether the person was employed),<br />
but the values of both variables were missing<br />
simultaneously. Third, in some cases,<br />
family income and personal earnings needed<br />
to be imputed within bounds because<br />
partial information was available about<br />
them (e.g., when a range was provided for<br />
family income, rather than an exact dollar<br />
value). Finally, several variables of various<br />
types (continuous, categorical, count) were<br />
used as predictors, but they sometimes had<br />
small amounts of missingness as well.<br />
I was involved in many aspects of this<br />
project (as with the bridging project), but<br />
especially in developing and evaluating the<br />
methods for imputation, writing technical<br />
documentation, and consulting with analysts<br />
using the multiply imputed data.<br />
An Exciting, yet Sometimes<br />
‘Scary,’ Job<br />
The two projects just described have several<br />
general characteristics in common. First,<br />
they required teamwork, both among staff<br />
at NCHS and between NCHS and other<br />
organizations. Second, they required statistical<br />
research. In fact, both projects led<br />
to publications in JASA [98(464) and<br />
101(475)]. Third, the problems were<br />
complicated, and they required making<br />
assumptions and implementing approximations<br />
for their solution. Finally, there<br />
was great interest in the data, and people<br />
both inside and outside the agency were<br />
clamoring for release of the data while the<br />
work was going on.<br />
Projects with the second through fourth<br />
characteristics create the need to “push the<br />
envelope” with regard to methodology<br />
under time constraints while maintaining<br />
the integrity of the data. This results in a<br />
job that is exciting, yet sometimes ‘scary.’<br />
Challenges and Opportunities<br />
<strong>Statistical</strong> work at NCHS, and in the<br />
government in general, is challenging<br />
for administrative and technical reasons.<br />
For example, budgets are tight; costs are<br />
increasing for data collection, processing,<br />
and dissemination; there is a desire on the<br />
part of policymakers, researchers, and others<br />
for more information; and the protection<br />
of confidentiality is becoming more<br />
difficult. Oh, yes, and let’s not forget the<br />
famous “graying of the federal work force,”<br />
with many employees nearing retirement<br />
age.<br />
Of course, with challenges come<br />
opportunities. Difficulties due to sparse<br />
resources and conflicting desires and constraints<br />
with regard to data will need to be<br />
addressed through the creative development<br />
of efficient methods for collecting<br />
new data and methods for getting the most<br />
out of analyses of existing data. And the<br />
‘graying’ work force will result in openings<br />
for new generations of statisticians to carry<br />
out such work. ■<br />

Kimiko Bowman<br />
Never Say Never<br />
Bowman Helps Provide Formula for Approximating the<br />
Distribution of Maximum Likelihood Estimators<br />
Val Snider<br />
ASA Publications Coordinator<br />
She could have been a horticulturist. She<br />
had, after all, thought it would be exciting<br />
to create new plants. But Kimiko Bowman,<br />
better known by her byline as K. O. Bowman,<br />
chose to be a statistician and help develop a formula<br />
for approximating the distribution of maximum<br />
likelihood estimators.<br />
It was by chance, really, that Bowman chose<br />
statistics. Some might even say statistics chose<br />
her. She began her college education majoring in<br />
home economics at Radford College. “I wanted<br />
to make sure I would graduate, and I thought<br />
home economics would be relatively easy,” said<br />
Bowman. “In my second year, the president of<br />
the college called me into his office and advised<br />
me to change my major to the science field. He<br />
thought my future would be much better in science.<br />
I [had] liked mathematics ever since I was a<br />
small child, so I immediately changed my major<br />
to math and chemistry.”
Kimiko Bowman, who became a U.S. citizen in 1958,<br />
was the first ‘foreigner’ to receive a doctorate from the<br />
University of Tokyo.<br />
About a year later, Bowman graduated with a<br />
bachelor’s degree and won a National Institutes<br />
of Health fellowship in mathematical statistics<br />
from Virginia Tech that sealed her interest in the<br />
statistics profession. Three years after that, she<br />
had in hand a master’s degree and PhD in statistics.<br />
She completed her education with a doctorate<br />
in mathematical engineering from Tokyo<br />
University, but it was during her time at Virginia<br />
Tech that her research really took hold.<br />
Bowman met L. R. Shenton, her thesis<br />
advisor, at Virginia Tech and—for the next<br />
45 years—worked with him to provide a formula<br />
for approximating the distribution of<br />
maximum likelihood estimators. They succeeded<br />
by developing formulae for skewness<br />
and kurtosis statistics of maximum likelihood<br />
estimators with respect to sample size and by<br />
developing an approximation formula for the<br />
percentage points of Pearson distributions.<br />
By combining the two results, Bowman and<br />
Shenton were able to approximate the distribution<br />
of maximum likelihood estimators.<br />
Another important accomplishment was<br />
successfully implementing a divergent series<br />
algorithm for large computers. “In sampling,<br />
statistics series like this often occur, and the<br />
algorithm for the coefficients is extremely<br />
complicated and reaches four-dimensional<br />
At Virginia Tech, Kimiko Bowman worked with L. R. Shenton, her thesis advisor, to provide a<br />
formula for approximating the distribution of maximum likelihood estimators.<br />
space,” said Shenton. Bowman not only implemented<br />
the algorithm, but “it works, thanks<br />
to Dr. Bowman,” said Shenton.<br />
Bowman’s life wasn’t all work, however. She also<br />
found time to be a strong advocate for those with<br />
disabilities. She served on the National Science<br />
Foundation Equal Opportunities in Science and<br />
Engineering advisory committee and Committee<br />
on People with Disabilities. She wrote a report<br />
while chairing the latter that resulted in grants<br />
being set aside to provide accommodation or<br />
special equipment for people with disabilities—<br />
which helped promote their participation in science<br />
and engineering at NSF.<br />
Bowman also chaired the <strong>Statistical</strong> Tracking of<br />
Employment of People with Disabilities task force<br />
for the President’s Committee on Employment of<br />
People with Disabilities. Her main duty was to<br />
monitor the questionnaire for Census 2000 so<br />
relevant questions were asked about people with<br />
disabilities and accurate results were obtained.<br />
Perhaps her interest in being a champion for<br />
people with disabilities stems from the physical<br />
hardships she, herself, has overcome. In her youth,<br />
Bowman suffered from polio that paralyzed<br />
her from the neck down. Doctors told her she<br />
would never walk again, but after two years of<br />
“ One must not<br />
lose sight of<br />
what we want<br />
to accomplish.<br />
So, I tried<br />
not to worry<br />
about slights<br />
or insignificant<br />
things.<br />
”<br />

rehabilitation, she was walking. Gladys Reynolds,<br />
a statistician and good friend of Bowman’s from<br />
her Virginia Tech years, said, “I want to highlight<br />
her determination and perseverance. … In 1980,<br />
she was having polio-like symptoms and was<br />
diagnosed with Post Polio Syndrome. In spite<br />
of this, she has continued to be as active and<br />
proliferate as always.”<br />
Bowman considers herself a “triple minority,”<br />
being an Asian and a woman, as well as someone<br />
who suffers the effects of polio. “There were<br />
many struggles I had to overcome,” Bowman<br />
said. “However, one must not lose sight of what<br />
we want to accomplish. So, I tried not to worry<br />
about slights or insignificant things.”<br />
Instead, she became one of the first women<br />
to be elected Fellow of the <strong>American</strong> <strong>Statistical</strong><br />
<strong>Association</strong> in 1976, worked hard to advance scientific<br />
research using statistics, advised a number of<br />
graduate students, and published three books and<br />
approximately 200 papers. One of those papers,<br />
“Tables for Determining <strong>Statistical</strong> Significance<br />
of Mutation Frequencies,” coauthored with M. A.<br />
Kastenbaum, received a Citation Classic in 1989<br />
for being the fourth most-cited paper in the history<br />
of Mutation Research, an international journal.<br />
Additionally, Bowman is an elected fellow of<br />
the <strong>American</strong> <strong>Association</strong> for the Advancement<br />
of Science (1970), an elected member of the<br />
International <strong>Statistical</strong> Institute (1978), and an<br />
elected fellow of the Institute of Mathematical<br />
Statistics (1987).<br />
Kimiko Bowman,<br />
at Virginia Tech,<br />
advised a number<br />
of graduate<br />
students<br />
and published<br />
three books and<br />
approximately<br />
200 papers.<br />
In an effort to do more for minorities in<br />
the statistics profession, Bowman also became<br />
a contributing editor to the Current Index to<br />
Statistics in 1977 and continued in this position<br />
for more than 10 years. During that time, she<br />
translated articles from Japanese journals into<br />
English, added keywords and abstracts, and<br />
included them in the index. She also was asked<br />
to go to Japan as a liaison scientist for the Office<br />
of Naval Research. She initially went for three<br />
months, but continued to visit throughout her<br />
career. In 1987, she was invited to attend the<br />
International <strong>Statistical</strong> Institute meeting in<br />
Tokyo and to give a keynote address at the satellite<br />
meeting at Mt. Fujiyama. During the meetings,<br />
she received an audience with the Crown Prince<br />
and Princess of Japan—an unforgettable memory<br />
for her.<br />
In 1994, Bowman retired from Oak Ridge<br />
National Laboratory as a senior research scientist.<br />
Retirement has not slowed her down,<br />
however. She continues to be a guest scientist<br />
in the Computational Sciences and Engineering<br />
Division at Oak Ridge, working on research in<br />
distributional properties of estimators and test<br />
statistics under non-normal sampling. She also<br />
consults with colleagues within Oak Ridge on<br />
aspects of statistics such as procedures for validating<br />
computer models in economics and stochastic<br />
models in epidemiology and biology. In the<br />
words of Reynolds, “As a woman, minority, and<br />
a person with a disability, she has certainly been<br />
an inspiration and mentor to many of us in the<br />
scientific community.” ■
Interview with<br />
Irene Hess<br />
Sampling Is in<br />
the Details<br />
Fritz Scheuren<br />
STATISTICIANS IN HISTORY<br />
Ida Irene Hess was born in Muhlenberg County, Kentucky. Her father was a mining engineer in Central<br />
City. Her mother, who graduated from Valparaiso College with her father, worked at home. After<br />
graduating from Indiana University, Hess returned to Central City to teach math and English at the<br />
local junior high school from 1932 to 1942. In 1940, she came to work with Leslie Kish at the Survey<br />
Research Center. Under Kish, she trained many graduate students in the details of sampling. The following<br />
is an interview with Hess, conducted in February 2008 by Fritz Scheuren, an ASA past-president.<br />
[Scheuren] Irene, it is so good to see you well and still active professionally<br />
at 97. Thanks for letting me interview you for all your<br />
many friends and colleagues who want to catch up with all you<br />
have done. Can we start with something about your family and<br />
early life before you came to the University of Michigan?<br />
[Hess] I grew up in Kentucky. In addition to my parents, I had<br />
one sister, Beulah Marie. I was at Evansville College three years<br />
and then went to Indiana University for one year for a bachelor’s<br />
degree, but that’s the only degree I have. I guess you want me to<br />
talk about my start as a sampler?<br />
[Scheuren] Well, of course, but a little more please about what<br />
you did before that. Didn’t you teach in high school?<br />
[Hess] No, I taught in junior high school in Central City,<br />
Kentucky. I was really not happy doing something like that,<br />
though. I was always interested in mathematics, and I would have<br />
liked teaching mathematics at a higher level. And, when you are<br />
teaching in public school, you first know that you’re to teach children.<br />
And I really didn’t enjoy that. I couldn’t enjoy grade-school<br />

mathematics. I did not want to be responsible for teaching children<br />
and encouraging them in what I would consider to be the<br />
‘right way.’<br />
So, I decided to try for statistical employment in the federal<br />
government. But to pass the civil service exam, you had to have<br />
a minimum of six hours in statistics and I did not have that, so I<br />
went about getting it. I considered Indiana first, but there wasn’t<br />
anything there that interested me at that time. I was aware of Iowa.<br />
Leslie [Kish] asked me once why I didn’t go to Iowa. I didn’t tell him<br />
why, but my mother’s parents lived in Iowa. It was always so hot<br />
in Iowa in the summer, so I just wouldn’t consider going to school<br />
in Iowa because I just couldn’t take that heat. I ordered catalogues<br />
from several universities—Indiana, Michigan, and Kentucky, perhaps<br />
others. I came to Michigan two summers (1940, 1941). That<br />
is how I got my six hours in statistics, and that was what I needed<br />
for the civil service exam, which I passed.<br />
[Scheuren] And you came to Washington after that?<br />
[Hess] Yes, it was right after the start of World War II in December<br />
and there was a civil service exam in May. The Bureau of Labor<br />
Statistics sent out invitations, and that’s what I applied for and<br />
went first to the Bureau of Labor Statistics. Then, I was at the<br />
Bureau of Standards for a short time when they were developing<br />
the proximity fuse for bombs in the war. When the war was over, I<br />
decided I better get away from the Bureau of Standards. Of course,<br />
I had already been here, at Michigan, for two years because I was<br />
really interested in statistics. So, I went out to the [U.S.] Census<br />
Bureau and talked to somebody out there. They were just organizing<br />
the first sampling section at the [U.S.] Census Bureau.<br />
Anyway, I joined the sampling section at the [U.S.] Census<br />
Bureau around 1944 or something like that. I was there until<br />
I came here in 1954. Kish was in charge of sampling here in<br />

Irene Hess (left and above) worked at the U.S. Census Bureau during the late ‘50s and stayed<br />
there until her retirement in 1981.<br />
Michigan, but his assistant was going to get married and move<br />
away and Kish needed somebody else. I was recommended to<br />
Kish and he wrote to me. In the meantime, at the [U.S.] Census<br />
Bureau, I think at least twice, when I came to work in the morning,<br />
they told me I should leave. I had no retention points to<br />
justify my continuing employment at the [U.S.] Census Bureau.<br />
(When a person returned from military service, that person had<br />
to be re-employed.)<br />
[Scheuren] They were laying off people?<br />
[Hess] Yes, that was because of the return of veterans from the<br />
war, and every time someone came back and had to have a job,<br />
they selected me to lay off. That happened twice. Joe Steinberg<br />
worked hard to get me back each time. Anyway, on one Good<br />
Friday evening, I walked into my apartment and picked up my<br />
mail and there was this communication from Leslie Kish out here<br />
in Michigan.<br />
When I got the letter, I felt it was going to be a job offer and<br />
I knew that I was going to take it, but I didn’t want to. I liked<br />
Washington and I always liked the [U.S.] Census Bureau. I<br />
responded to Leslie’s letter, and he invited me here to look around.<br />
I’ve been here ever since, and that was 1954. In 1981, I retired. I’ve<br />
been retired for 27 years.<br />
[Scheuren] But you’ve been working here as a retired person,<br />
every weekday ever since? That’s a real compliment to you<br />
and to the center.<br />
[Hess] Well it has been a long time. The way it began was I had<br />
started this book [on sampling]. We had some very complex sample<br />
designs for various projects and it bothered me that nobody else<br />
around here knew anything about the sampling activities. So, I had<br />
written or was working on that book, Sampling for Social Survey<br />
Research Surveys, 1947–1980. I decided to stay and finish it.<br />
[Scheuren] So, that is how you are continuing to work after retirement?<br />
What came next that kept you coming here every day?<br />
[Hess] Roe Goodman. I don’t know if you were ever acquainted<br />
with Goodman.<br />
[Scheuren] No, I wasn’t, but I know of his work.
Irene Hess worked with Leslie Kish, but<br />
also worked with Mildred “Jean” Harter,<br />
seen here with Hess (above and right) in<br />
Hess’ office in the late ‘50 s.<br />
[Hess] Goodman was sold on controlled selection.<br />
[Scheuren] Well, I am too. In fact, one of my former students,<br />
Yan Liu, did her dissertation on balanced sampling with me—a<br />
related idea.<br />
[Hess] Goodman’s family was here in Michigan, so he came in one<br />
day concerned about how well-controlled selection by computer<br />
is compared with hand-drawn controlled selection. So, that’s how<br />
we happened to have the book Controlled Selection Continued. As<br />
I remember it, I think we were already well into the book before I<br />
had to retire.<br />
[Scheuren] You had to retire because of age? What was the age<br />
you had to retire?<br />
[Hess] Yes, I had to retire at 70. That was in 1981.<br />
Anyway, Goodman was very interested in controlled selection and<br />
the material we set up and worked on in the book. The last time<br />
I saw Goodman was one afternoon before Easter. Goodman’s wife<br />
was already in Kansas and he was going to go take the train and<br />
join her. Anyway, he put in his final edits to the book. We didn’t<br />
know they were final edits, of course, at the time. Well, he went<br />
home to Kansas. He had a heart attack and died that night. That<br />
made me determined to finish the book.<br />
When my time came to retire, I probably still had something<br />
to do there. I don’t know if it was all done—probably not. I don’t<br />
remember how long it took me to get these first two books finished<br />
after I retired.<br />
[Scheuren] But there were more books after that weren’t there?<br />
Leslie Kish, ASA president in 1977;<br />
he passed away in 2000.<br />
[Hess] Yes, several. The last one of these was published in<br />
September 2007, I think.<br />
[Hess, changing the subject] As you know, the center has done a lot<br />
of work on telephone surveys. But, I never got very deeply into the<br />
telephone field. All of these things I worked on were face-to-face<br />
area probability surveys. I believed wholeheartedly in this approach.<br />
And, hence, I never got involved in the telephone business.<br />
How it started at the center was Charlie Cannell and Bob Kahn<br />
got a project to work on telephone sampling. One day, I don’t<br />
know if it was Cannell or Kahn, asked me if there was somebody in<br />
the sampling section who could work with them on this telephone<br />
project they had and I told them Bob Groves. And, I also told Bob<br />
Groves that Cannell and Kahn would be talking to him. And they<br />
did, and they worked on various projects, and Groves has been<br />
with telephone surveys ever since. I was no admirer or interested in<br />
the telephone. Anyway, I was getting to the point where I had to<br />

retire, so it was not something for me to get into and I had enough<br />
of these other things [talked about earlier] to finish up.<br />
[Scheuren] You sure did. Look at these accomplishments, all done<br />
after you retired, too.<br />
[Hess] Now, I’m completely out of any project and I don’t have<br />
anything that I really want to write about. So, I figure I ought to<br />
clean up everything that I have around here and get out.<br />
[Scheuren] Don’t do that. You do have more to do. At least help<br />
me edit this interview, please?<br />
[Hess] Bob Groves says he just likes to have me around.<br />

[Hess] Early on, I did publish a number of papers with Kish. I<br />
remember a paper in The <strong>American</strong> Statistician on nonresponse.<br />
That paper was something I guess Kish shared with me, actually.<br />
That was just shortly after I came here.<br />
[Scheuren] That nonresponse paper that you and Kish did is a<br />
wonderful piece of applied work. I have cited it many times. When<br />
I used to do the History Corner in The <strong>American</strong> Statistician, I<br />
republished it.<br />
[Hess] After about 1960, Kish got out of the day-to-day sampling<br />
activities. He was going to educate the world. So, we didn’t work<br />
together much after that. For example, he did not have anything to<br />
do with the projects that I was working on and what we were doing<br />
with Roe Goodman. Kish was not involved with any of that. He<br />
was just in a separate area of the center completely.<br />
[Scheuren] One last item? Can you talk about your involvement<br />
with the Section on Survey Research Methods?<br />
[Hess] Do you know how the section started? Within the Social<br />
Statistics Section, there was a subsection, and I guess it existed for<br />
maybe two or three years. But anyway, at one time, I was nominated<br />
for chair of the subsection. There was an election within the<br />
Social Statistics Section and I happened to have been nominated<br />
and then elected for chair of the subsection. In the meantime,<br />
the powers that be decided to have a separate section for survey<br />
research, and they said—because I had just won the election—<br />
that I would automatically be chair of the new Section on Survey<br />
Research Methods. So, I was the first chair of the Section on Survey<br />
Research Methods, 1977.<br />
Do you remember this [showing the engraved silver plate given<br />
to her by the Section on Survey Research Methods in 1998]?<br />
[Scheuren] You still have this? I remember it well. I think I may<br />
even have given it to you.<br />
[Hess] That was my last annual meeting. I remember it very well.<br />
I was surprised, overwhelmed.<br />
[Scheuren] Irene, you have done such wonderful things for us all.<br />
I’m going to read this inscription. The inscription says, “Irene Hess<br />
for distinguished service and unstinting efforts in the furtherance<br />
of survey research methods.”<br />
[Hess] In July 1999, I had extensive surgery on my right leg, and<br />
I have never been free of some kind of health struggle since that<br />
time. And I have never been to another meeting of the <strong>American</strong><br />
<strong>Statistical</strong> <strong>Association</strong>, and I guess I’ll never get there again. But<br />
anyway, 1998 was very special. That was a real graduation for me.<br />
[Scheuren] Oh my, you’ve done so many things, Irene, and most<br />
of your major publications were finished after you retired. Earlier,<br />
you were so busy day-to-day that you didn’t have time to write<br />
these books. But, you did write them, eventually. How can we all<br />
thank you? ■
Jack Chao-sheng Lee<br />
The following excerpt is based on the 2007 article “In Memory<br />
of Professor Jack Chao-sheng Lee (1941–2007),” which<br />
appeared in the Journal of Data Science, Vol. 5, 143–150. For<br />
a complete version, visit www.sinica.edu.tw/~jds/In-memory-of-<br />
Jack-Lee.pdf.<br />
Chao-sheng Lee can be described as one of the most outstanding<br />
people in Taiwan’s present statistical community.<br />
His 40-year career of teaching and research has resulted in<br />
nearly 100 academic papers in well-known international periodicals.<br />
The National Chiao Tung University (NCTU) Graduate<br />
Institute of Statistics, where Lee established himself when he<br />
returned from the United States, has become a cornerstone for the<br />
development of Taiwan’s growing statistical academic circles. The<br />
NCTU Graduate Institute of Finance, which Lee helped establish,<br />
has provided Taiwan’s financial sector with the talent needed<br />
for growth and innovation.<br />
Lee graduated from National Taiwan University’s Department<br />
of Business in 1964 and received his master’s in economics from<br />
the University of Rochester in 1969. He studied under Seymour<br />
Geisser at The State University of New York, Buffalo, and received<br />
his PhD in statistics in 1972. Upon completing his education, he<br />
began his teaching career at the University of Minnesota, and then<br />
taught at Wright State University, as well as other universities, for<br />
many years. He then went to Bell Labs and devoted himself to<br />
research in economics and statistics.<br />

In 1992, Lee was invited by Chi-Fu Den, the president of<br />
NCTU, and Tsang-Hai Kuo, the dean of the College of Science,<br />
to return to Taiwan and take up the post of chair of the newly<br />
established Institute of Statistics. Until stepping down from this<br />
post in 1999, he persuaded many top statistical researchers who<br />
had graduated from well-known schools to return to Taiwan<br />
and teach. He also encouraged the now common practice of<br />
research and acquiring software, as well as hardware. His efforts<br />
enabled the Institute of Statistics at NCTU to quickly rise<br />
to the level of other established institutes of statistics, namely<br />
those of National Tsing-Hua University and National<br />
Central University.<br />
In August 1995, Lee was the first academic in Taiwan to<br />
receive the ASA Fellow honor from the <strong>American</strong> <strong>Statistical</strong><br />
<strong>Association</strong>. Lee had already been selected as a member of the<br />
International <strong>Statistical</strong> Institute in 1990 and elected as the<br />
president of the International Chinese <strong>Statistical</strong> <strong>Association</strong> in<br />
1992. He was invited on multiple occasions to make speeches<br />
around the world in many renowned schools, including<br />
Harvard, Columbia, Cornell, and [the] University of Minnesota<br />
in the United States; Oxford and [the] University of London in<br />
England; Hitotsubashi University and Kobe University in Japan;<br />
[the] University of British Columbia in Canada; and INSEAD<br />
in France, to name a few.<br />
12 AMSTAT NEWS SEPTEMBER 2008<br />
In order to adapt to the trend of global financial development,<br />
Lee participated in the establishment of the Institute of Finance<br />
at NCTU in 2002 and took on the responsibility of head of the<br />
institute for two years. During his tenure in charge, he was elected<br />
University Chair Professor of NCTU in recognition of his dedication<br />
and accomplishments, as well as his reputation within academic<br />
circles.<br />
Lee had published many papers, and his research subjects<br />
included many fields in statistics, including multivariate analysis,<br />
time series analysis, growth curves, Bayesian inference, and classification<br />
and pattern recognition. He also published in other areas,<br />
such as portfolio management and option evaluation, with particular<br />
application to finance.<br />
Lee conducted his academic studies conscientiously. Since his<br />
return to Taiwan, he has supervised numerous exceptional master’s<br />
and PhD graduates. He has four PhD graduates who are currently<br />
teaching in well-known universities and colleges. His master’s<br />
graduates have also held pivotal positions in numerous areas of<br />
business and academia. His pupils owe much to him, and have the<br />
capability to build on his success and to further glorify what Lee<br />
has started.<br />
Throughout his life, Lee lived plainly and simply, and his passion<br />
for learning never diminished. He, now and always, will be a<br />
great role model for scholars to admire and learn from. ■
Paul Dixon Minton<br />
Building a<br />
Department<br />
Dwight B. Brock,<br />
Westat<br />
Paul Dixon Minton was born in Dallas,<br />
Texas, the third of four sons in the family<br />
of William M. and Addie Evelyn Croft<br />
Minton. Having grown up in the economically<br />
difficult times of the Great Depression, he was<br />
able to attend college only because he received an<br />
“emergency scholarship” to attend Southern<br />
Methodist University (SMU). The university was<br />
experiencing its own difficulties, struggling to fill<br />
classes, and decided to offer such scholarships to<br />
young Dallasites who had done well in high<br />
school, were recommended by their principals,<br />
and could not otherwise afford to go to school.<br />
Minton earned a bachelor’s and master’s<br />
degree from SMU, a school to which he would<br />
return later to found and direct a department of<br />
statistics. His studies were interrupted by World<br />
War II, during which time he worked as a cryptanalyst<br />
for the FBI. Following the war, he returned<br />
to Dallas as an instructor and graduate student<br />
STATISTICIANS IN HISTORY<br />
at SMU in the Department of Mathematics. It<br />
was at that point that Minton was introduced to<br />
probability and statistics by Edwin Mouzon, who<br />
had, himself, written a dissertation on statistics<br />
at the University of Illinois. After completing<br />
his master’s degree, Minton was encouraged by<br />
Mouzon to continue his graduate studies in the<br />
new program in statistics at The University of<br />
North Carolina.<br />
Minton earned a PhD in statistics from<br />
North Carolina State University under the<br />
tutelage of Gertrude Cox, during the time the<br />
Institute of Statistics of the Greater University<br />
of North Carolina consisted of the Department<br />
of Mathematical Statistics at UNC Chapel Hill<br />
and the Department of Experimental Statistics<br />
at NC State in Raleigh. Many famous statisticians<br />
were either faculty members or visitors<br />
when Minton was a student there, including<br />
R. A. Fisher, Harold Hotelling, William Cochran,<br />

William Cochran<br />
14 AMSTAT NEWS SEPTEMBER 2008<br />
Jacob Wolfowitz, Herbert Ellis Robbins, Richard<br />
L. Anderson, Raj Chandra Bose, and others too<br />
numerous to mention.<br />
Minton once related a story in which Fisher was<br />
sitting in the front row of the audience when he<br />
(Minton) gave his first paper as a graduate student.<br />
As if that fact alone was not enough to frighten<br />
an already nervous graduate student, the situation<br />
became “infinitely worse” (Minton’s words)<br />
when Fisher left the room in the middle of the talk.<br />
Minton told another story about his final PhD oral<br />
examination, in which he had a bad case of laryngitis<br />
that he attributed to nerves. To his knowledge,<br />
he had the world’s only silent orals.<br />
Minton returned once again to SMU and<br />
began to build a set of courses in mathematical and<br />
applied statistics for students from a wide range of<br />
subject-matter departments in the university. These<br />
offerings gradually evolved into the formation of<br />
the Department of Statistics at SMU, now known<br />
as the Department of <strong>Statistical</strong> Science. At the<br />
same time, Minton began to recognize the importance<br />
of computing in statistics, and, as a result of<br />
his expressed opinions, he was assigned to direct the<br />
first computer center at SMU, which housed the<br />
Univac 1103, one of the few large scientific computers<br />
available at the time.<br />
Funded primarily by a training grant from the<br />
National Institutes of Health for training biostatisticians,<br />
Minton established a new Department<br />
of Statistics at SMU in 1962. It was significant<br />
in obtaining faculty approval of the new department<br />
that he had provided research consultation in<br />
either statistics or computing—or both—to every<br />
department in the university. The new department<br />
offered master’s and doctoral degrees following the<br />
North Carolina model and received consultation<br />
and assistance from Cox. The department subsequently<br />
expanded to offer degrees at all levels, to<br />
provide consultative assistance to faculty research<br />
and outside clients, and to conduct research in statistical<br />
theory and methods.<br />
After 10 years of developing and administering<br />
the SMU department, Minton moved to<br />
Richmond, Virginia, to take the position of<br />
dean of the School of Arts and Sciences at<br />
Virginia Commonwealth University in 1972.<br />
There, in addition to his duties as dean, Minton<br />
formed an Institute of Statistics—a form of<br />
liaison office between the Department of<br />
Mathematical Sciences in the School of Arts and<br />
Sciences and the Department of Biostatistics in<br />
the Medical College of Virginia. He also was<br />
active in statistical consulting in local industry,<br />
including paper manufacturing, polymer plastics<br />
processors, pharmaceuticals, a national baking<br />
company, and a federal agency. He retired from<br />
VCU in 1988. That year, a special symposium<br />
was organized in his honor, attended by many<br />
former students and colleagues.<br />
Minton was the recipient of numerous academic<br />
and professional awards, including being named a<br />
Fellow of the <strong>American</strong> <strong>Statistical</strong> <strong>Association</strong> and<br />
being an early recipient of the ASA Founders Award<br />
for service to the association and the profession. In<br />
his honor, the SMU Statistics Department created<br />
the Paul Minton Award for the student who scores<br />
highest on the basic qualifying examination. Also,<br />
the ASA created the Paul Minton Service Award,<br />
which has been given annually since 1992. He was a<br />
longtime member of the ASA, IMS, and Biometric<br />
Society. He founded the North Texas Chapter of<br />
the ASA and was active in a variety of roles during<br />
the years he was in Dallas. Later, he was very<br />
active with the Virginia Academy of Sciences (the<br />
Virginia Chapter of the ASA) and in organizing the<br />
Southern Regional Conferences on Statistics. He<br />
participated in numerous committees, task forces,<br />
councils, and boards, and he served one term as<br />
vice president of the ASA.<br />
Minton had an active life outside the statistics<br />
profession that included a love of classical<br />
music and the ability to create terrible puns. He<br />
combined those interests with his knowledge of<br />
statistics in the following way. As part of the<br />
ASA’s 150 celebration in 1989 in Washington,<br />
DC, he and some friends created a “statistical<br />
songbook,” from which they performed at<br />
a banquet held on that occasion. In the hands<br />
of these statistical punsters, the tune “Bali<br />
Hai” from the musical “South Pacific” became<br />
the results for a test of statistical significance:<br />
“Barely High.” These and other rewritten song<br />
lyrics can be found in the songbook, which was<br />
subsequently published in the August 1990<br />
issue of The <strong>American</strong> Statistician.<br />
In a sense, entertaining audiences with humorous<br />
statistical lyrics to well-known songs became<br />
another way for Minton to be an advocate for<br />
statistics and promote the profession to a wider<br />
world. His life and work as a statistician were<br />
summarized at his memorial service in the words<br />
of his son, Roland: “He recruited students to<br />
the newly developing field of statistics, he found<br />
money to support them during their student<br />
days, and he helped them find jobs after they<br />
graduated. Others have said of him that he was<br />
a gentle person, with a gentle temperament, but<br />
he changed the lives of hundreds, if not thousands<br />
of statistical students, just as he changed<br />
the lives of many others who knew him outside<br />
the profession.”<br />
A memorial session for Minton was held at the<br />
2008 Joint <strong>Statistical</strong> Meetings in Denver. Papers<br />
from that session will be included in the ASA<br />
Archives Collection at Iowa State University. ■
<strong>Mollie</strong> <strong>Orshansky</strong>:<br />
Author of<br />
the Poverty<br />
Thresholds<br />
Gordon M. Fisher<br />
<strong>Mollie</strong> <strong>Orshansky</strong> was born on January 9,<br />
1915, in the Bronx in New York City.<br />
She was the daughter of Ukrainian-<br />
Jewish immigrants who spoke limited English.<br />
Although her father worked hard at a number of<br />
jobs, <strong>Orshansky</strong> and her sisters grew up poor—in<br />
her words, the family could “barely … make ends<br />
meet.” The girls slept two to a bed and wore handme-down<br />
clothing. <strong>Orshansky</strong> remembered going<br />
with her mother to stand in relief lines for surplus<br />
food. As she was to say later, “If I write about the<br />
poor, I don’t need a good imagination—I have a<br />
good memory.”<br />
<strong>Orshansky</strong> was both the first high-school<br />
graduate and first college graduate in her family.<br />
She graduated from Hunter College High School<br />
in Manhattan (then a school for gifted young<br />
women) in 1931. Because she received two scholarships<br />
from the college, she was able to attend<br />
Hunter College (at that time a women’s college).<br />
She graduated from Hunter in 1935 with an AB<br />
in mathematics and statistics. She was a statistician<br />
by training and profession, although she has sometimes<br />
been referred to as an economist.<br />

Editor’s Note: Views expressed in this article are those of the author, and should not be construed as representing the<br />
policy of the U.S. Department of Health and Human Services. This article is condensed from an unpublished draft<br />
paper with references. That paper is based on extensive research involving published articles and documents, unpublished<br />
documents, and conversations with <strong>Mollie</strong> <strong>Orshansky</strong>.<br />
A daughter from a poor family graduating from<br />
college during the Great Depression, <strong>Orshansky</strong> did<br />
not have the luxury of attending graduate school<br />
before she started working. Instead, she found a job<br />
as a statistical clerk in the New York Department of<br />
Health’s Bureau of Nursing, where she worked on<br />
infant mortality and other subjects for a year.<br />
In 1936, the U.S. Children’s Bureau (then part of<br />
the U.S. Department of Labor) offered <strong>Orshansky</strong> a<br />
job as a junior statistical clerk. She accepted the job,<br />
moving from New York to Washington, DC. Her<br />
first job assignment involved logarithmic equations<br />
for 600 infants who had been in a study. In July<br />
1939, the bureau promoted her to research clerk, a<br />
job in which she stayed until January 1942, working<br />
on biometric studies of child health, growth,<br />
and nutrition.<br />
It was while she was working at the U.S.<br />
Children’s Bureau that <strong>Orshansky</strong> began taking<br />
graduate courses. At various times between 1936–<br />

STATISTICIANS IN HISTORY<br />
How <strong>Mollie</strong> <strong>Orshansky</strong><br />
Developed the Poverty Thresholds<br />
When <strong>Orshansky</strong> developed her poverty thresholds, she<br />
made use of information she had worked with at the U.S.<br />
Department of Agriculture (USDA). She based her thresholds<br />
on the economy food plan, which was the cheapest of four<br />
food plans (hypothetical food budgets providing nutritious<br />
diets at different cost levels) developed by USDA.<br />
From a finding of USDA’s 1955 Household Food Consumption<br />
Survey (the latest such survey available during the early<br />
1960s), she knew families of three or more persons had spent<br />
approximately one-third of their after-tax money income on<br />
food in 1955. The way in which she used this survey finding<br />
was by considering a hypothetical average family that was<br />
spending one-third of its income on food and by assuming<br />
the family had to cut back on its expenditures sharply. She<br />
assumed expenditures for food and non-food would be cut<br />
back at the same rate so the family would continue to spend<br />
a third of its income for food.<br />
When the food expenditures of the hypothetical family<br />
reached the cost of the economy food plan, she assumed<br />
the amount the family would spend on non-food items<br />
would also be minimal, but adequate. (Her procedure did<br />
not assume specific dollar amounts for any budget category<br />
besides food.) Following this logic, she calculated poverty<br />
thresholds for families of various sizes by taking the dollar<br />
costs of the economy food plan for families of those sizes and<br />
multiplying the costs by a factor of three—the “multiplier.”<br />
(She followed somewhat different procedures to develop<br />
thresholds for two-person and one-person units.)<br />
She differentiated her thresholds not only by family size, but<br />
by farm/nonfarm status, by the gender of the family head, by<br />
the number of family members who were children, and (for<br />
one- and two-person units only) by aged/non-aged status.<br />
The result was a detailed matrix of 124 poverty thresholds, later<br />
reduced to 48.<br />
To avoid confusion, the preceding explanation has been<br />
phrased in terms of the economy food plan. However,<br />
<strong>Orshansky</strong> actually developed and discussed two sets of<br />
poverty thresholds, one derived from the economy food plan<br />
and one derived from the somewhat less stringent low-cost<br />
food plan. (The latter set was the one she preferred.) It was the<br />
lower of the two sets of poverty thresholds—the set derived<br />
from the economy food plan—that the Office of Economic<br />
Opportunity adopted as a working definition of poverty in<br />
May 1965. One probable reason for the adoption of the lower<br />
set of thresholds was that the lower set yielded approximately<br />
the same number of persons in poverty as the Council of<br />
Economic Advisers’ $3,000/$1,500 poverty line.<br />

as a statistician for the New York City Department of Health, working<br />
on a survey of the incidence and therapy of pneumonia.<br />
Talking about her government career, <strong>Orshansky</strong> once commented,<br />
“I basically always worked with women, except when I was in the<br />
war agencies [the National War Labor Board during World War II<br />
and the Wage Stabilization Board during the Korean War].” During<br />
World War II, in particular, large numbers of men left civilian jobs to<br />
serve in the military. As a result, a number of female workers were able<br />
to get jobs that would not have been open to them under ‘normal’<br />
circumstances. Describing the situation for female federal workers,<br />
Dorothy Rice, a colleague of <strong>Orshansky</strong>’s, later said, “Any female that<br />
had anything on the ball really did very well during the war. All the<br />
men went to the war and we had to carry on.”<br />
In March 1943, <strong>Orshansky</strong> secured a job at the U.S. National War<br />
Labor Board as chief of the Program Statistics Division of the Research<br />
and Statistics Branch. She planned and executed the collection and<br />
analysis of data required for the board’s decisions on wage adjustments<br />
and the effects of the board’s stabilization activities. She stayed in this<br />
job until September 1945, when the operations of the board were<br />
being terminated.<br />
From September 1945 to March 1951, <strong>Orshansky</strong> worked as<br />
a family economist at the Bureau of Human Nutrition and Home<br />
Economics of the U.S. Department of Agriculture (USDA). She conducted<br />
research in family consumption and levels of living, carrying<br />
out a variety of assignments. She was in charge of preparing data on<br />
the estimated value of household furnishings and equipment on farms<br />
for the department’s balance sheets of agriculture for 1947–1950.<br />
In 1948, <strong>Orshansky</strong> and a colleague were responsible for responding<br />
to letters from members of the public asking how they could make<br />
ends meet on their existing income in the face of the severe (by U.S.<br />
standards) post–World War II inflation. <strong>Orshansky</strong> and her colleague<br />
would send the letter writers pamphlets about preparing a family budget<br />
and planning low-cost and moderate-cost meals using USDA’s<br />
food plans—hypothetical food budgets providing nutritious diets at<br />
different cost levels. (This shows <strong>Orshansky</strong> was working with USDA’s<br />
food plans at least 15 years before she was to use them to develop her<br />
poverty thresholds.)<br />
About 1949, <strong>Orshansky</strong> carried out an assignment to update a standard<br />
budget (an estimate of necessary living costs) for a single working<br />
woman in New York. In June 1950, she presented a paper titled<br />
“Equivalent Levels of Living: Farm and City” at the annual meeting<br />
of the Conference on Research in Income and Wealth (CRIW). Her<br />
paper and the other papers presented at the meeting (including one<br />
by Milton Friedman) were published in volume 15 of CRIW’s annual<br />
(and still continuing) series, Studies in Income and Wealth.<br />
In March 1951, during the Korean War, <strong>Orshansky</strong> secured<br />
a job at the U.S. Wage Stabilization Board as the director of the<br />
Program Statistics Division of the Office of Economic Analysis. She<br />
planned and directed the board’s statistical program until August<br />
1953, when the operations of the board were being terminated due<br />
to the end of the war.<br />
In 1952, while <strong>Orshansky</strong> was working at the U.S. Wage<br />
Stabilization Board, she was elected a member of the Econometric<br />
Society (an international society for the advancement of economic<br />
theory in its relation to statistics and mathematics). Of the 73 candidates<br />
for election to membership in 1952, <strong>Orshansky</strong> was the<br />
only woman.
From August 1953 to February 1958, <strong>Orshansky</strong> worked as a food<br />
economist for USDA in a successor office to the Bureau of Human<br />
Nutrition and Home Economics, where she had worked before. She<br />
planned and directed the collection and analysis of data on food consumption<br />
and expenditures of <strong>American</strong> households.<br />
In 1956 and 1957, <strong>Orshansky</strong> was the senior coauthor of two<br />
reports on family food expenditures and food consumption based on<br />
a food consumption survey of rural families in the North Central<br />
[Midwest] region. She was one of a number of people who gave technical<br />
assistance in the preparation of a series of reports on USDA’s<br />
1955 Household Food Consumption Survey, and she wrote a<br />
major section of a summary report on the same survey. This 1955<br />
Household Food Consumption Survey was the source from which<br />
<strong>Orshansky</strong> would calculate the “multiplier” she later used to develop<br />
her poverty thresholds.<br />
In February 1958, <strong>Orshansky</strong> went to work for the Social Security<br />
Administration (SSA) in an office that later became the Office of<br />
Research and Statistics (ORS). ORS seems to have been one of a<br />
small number of federal offices that provided significant work opportunities<br />
for women professionals at this time; during <strong>Orshansky</strong>’s first<br />
decade there, both the director and the deputy director were women.<br />
<strong>Orshansky</strong> had several titles at SSA, but can best be described as a<br />
social science research analyst.<br />
<strong>Orshansky</strong> performed a number of assignments during her early<br />
years at SSA. Her first was to prepare an article on standard budgets<br />
(family budgets) and practices in setting fee scales in 21 large cities.<br />
She also prepared several annual updates of an analysis of the income<br />
sources of “young survivors” (widows under age 65, particularly those<br />
with minor children). She prepared a medical care standard for the<br />
Budget for an Elderly Couple, of which the Bureau of Labor Statistics<br />
(BLS) was preparing an interim revision. She also prepared data for<br />
16 charts on financial resources of the aged for the Chart Book for the<br />
1961 White House Conference on Aging.<br />
While <strong>Orshansky</strong>’s development of the poverty thresholds was a<br />
major milestone in both social policy history and statistical history, it<br />
grew out of ordinary work activities—an “answer for the record” for<br />
a congressional hearing and an in-house research project. During a<br />
1960 congressional hearing, a senator asked HEW Secretary Arthur<br />
Flemming if he had figures on how much it costs a retired couple to<br />
live. Flemming said HEW would provide an answer for the record,<br />
and <strong>Orshansky</strong> was the civil servant who prepared an unattributed<br />
submission for the record. She mentioned the Budget for an Elderly<br />
Couple, which BLS was then revising, and a similar budget prepared<br />
by a group in New York. In addition, she provided two rough measures<br />
of income inadequacy for an elderly couple that she developed<br />
by applying multipliers derived from USDA’s 1955 Household Food<br />
Consumption Survey to the cost of USDA’s low-cost food plan (at that<br />
time, the cheapest of USDA’s three food plans)—almost exactly as she<br />
was to do several years later in her 1963 and 1965 poverty articles.<br />
In early 1963, <strong>Orshansky</strong> was assigned to do an in-house research<br />
project on poverty as it affects children. At that time (the year before<br />
the War on Poverty was declared), there was no generally accepted<br />
measure of poverty, so to carry out this research project, <strong>Orshansky</strong><br />
developed one (see “How <strong>Mollie</strong> <strong>Orshansky</strong> Developed the Poverty<br />
Thresholds” on the previous page for her methodology). In July 1963,<br />
she published results of her research project in a Social Security Bulletin<br />
article, “Children of the Poor,” in which she also described the initial<br />
version of her poverty thresholds.<br />
<strong>Orshansky</strong> told several interesting stories about<br />
events during the development of her thresholds:<br />
➤ As noted in the sidebar, “How <strong>Mollie</strong> <strong>Orshansky</strong> Developed the<br />
Poverty Thresholds,” <strong>Orshansky</strong> based her thresholds on USDA’s<br />
economy food plan. She had been working with the USDA food<br />
plans at least as early as 1948, and so was familiar with them. In<br />
the context of developing poverty thresholds for families, she<br />
became concerned about the economy food plan not allowing<br />
for purchases of food away from home, either at work or school.<br />
For the purpose of developing poverty thresholds, she wanted<br />
to modify the cost of the food plan by adding $0.15 a day per<br />
person to it to allow for the husband in a family to buy coffee<br />
at work or for children to buy snacks. However, her supervisor<br />
would not allow her to do so.<br />
➤ One major source for <strong>Orshansky</strong>’s July 1963 article was a<br />
special tabulation of Current Population Survey (CPS) data that<br />
the Social Security Administration (SSA) purchased from the<br />
U.S. Census Bureau for $2,500. The results showed the median<br />
annual income of nonfarm, female-headed families with<br />
children was $2,340. <strong>Orshansky</strong> was horrified when she realized<br />
half of these families lived for a year on less than SSA paid for<br />
one statistical tabulation. She later commented, “I determined I<br />
was going to get my $2,500 worth.”<br />
➤In the CPS, thousands of sample cases represent millions<br />
of families and persons in the general population. Published<br />
U.S. Census Bureau reports based on survey data always<br />
show figures that relate to the national totals of families and<br />
unrelated individuals. However, when <strong>Orshansky</strong> got the results<br />
of her $2,500 tabulation of CPS data, they gave her only the<br />
unweighted counts of sample households in various poverty<br />
and nonpoverty categories; SSA’s payment to the bureau had<br />
not been enough to pay for computing weighted national<br />
totals for her, so she had to do the work herself, “by hand,” to<br />
calculate weighted national totals from the unweighted sample<br />
count. She also calculated the poverty gap “by hand” for her<br />
January 1965 article. She didn’t even use a calculator.<br />
In January 1964—only six months after the publication of<br />
<strong>Orshansky</strong>’s obscure article—President Lyndon Johnson declared a<br />
war on poverty. In a chapter on the problem of poverty in its 1964<br />
annual report, the president’s Council of Economic Advisers (CEA)<br />
put forward its own rough measure of poverty: $3,000 for families<br />
of all sizes and $1,500 for unrelated individuals. The CEA’s $3,000<br />
figure was not derived in any way from <strong>Orshansky</strong>’s work; however,<br />
the CEA report did cite two dollar figures from <strong>Orshansky</strong>’s July 1963<br />
article (without giving her name as the author) to show that the CEA’s<br />
$3,000 figure was a reasonable level for a poverty line.<br />
When <strong>Orshansky</strong> saw the January 1964 CEA report (including the<br />
reference to her dollar figures), she was disturbed by the CEA’s failure<br />
to vary its $3,000 family poverty line by family size, as this resulted<br />
in understating the number of children in poverty relative to aged<br />
persons. The CEA figure “led to the odd result that an elderly couple<br />

<strong>Mollie</strong> <strong>Orshansky</strong> (third from left) at the first Conference on Women in the War on Poverty on May 8, 1967. With her are Mary Keyserling, Josephine<br />
Weiner, and Hyman Bookbinder. Near the end of her speech, <strong>Orshansky</strong> said, “…our statistics, imperfect though they may be, show us where problems<br />
are even if they cannot always reveal exact dimensions…[C]alculations … relating to poverty … exist only to help make them disappear, and so<br />
if we can think bold solutions and dream the big dream, we can wipe out the scourge of poverty before we all agree on how to measure it.”<br />
with $2,900 income … would be considered poor, but a family with<br />
a husband, wife, and four little children with $3,100 income would<br />
not be.” In addition, the president’s declaration of a war on poverty<br />
evidently led SSA to give a higher priority to <strong>Orshansky</strong>’s poverty<br />
work. As a result, <strong>Orshansky</strong>’s supervisors asked her to do an analysis<br />
extending her families-with-children poverty thresholds to the whole<br />
population. She completed this analysis in late 1964 and it was published<br />
in the Social Security Bulletin in January 1965 as “Counting the<br />
Poor: Another Look at the Poverty Profile.”<br />
The publication of <strong>Orshansky</strong>’s January 1965 article came when<br />
the Office of Economic Opportunity (OEO)—the lead agency for<br />
the War on Poverty—was being set up. OEO officials were enthusiastic<br />
about <strong>Orshansky</strong>’s poverty thresholds, considering them to be<br />
an advance over the CEA’s $3,000-for-all-family-sizes figure. OEO<br />
research chief Joseph Kershaw commented, “<strong>Mollie</strong> <strong>Orshansky</strong> says<br />
that when you have more people in the family, you need more money.<br />
Isn’t that sensible?” In May 1965, OEO adopted <strong>Orshansky</strong>’s thresholds<br />
as a working definition of poverty for statistical, planning, and<br />
budget purposes, and, in August 1969, her thresholds were made the<br />
federal government’s official statistical definition of poverty.<br />
When she developed the poverty thresholds, <strong>Orshansky</strong> was “an<br />
obscure civil servant” who worked “[d]own a dimly lit hall, among<br />
stacks of computer printouts [at] a paper-covered desk …” However,<br />
after her thresholds were adopted as the federal government’s poverty<br />
line, she became much more well known. Because of frequent citations<br />
of her work in academic articles and books, someone once referred to<br />
her as “the ubiquitous footnote.” Besides presenting papers at a number<br />
of professional meetings and publishing a number of articles, she<br />
testified and/or provided written documents to congressional committees<br />
on 10 occasions between December 1967 and 1990.<br />
On five occasions between 1968 and 1980, <strong>Orshansky</strong> participated<br />
in federal interagency committees that reviewed the poverty thresholds.<br />
The 1968–1969 committee made two modest revisions in<br />
the thresholds, and it was the thresholds with these revisions that<br />
were made the official federal statistical definition of poverty. In<br />
1981, several minor changes recommended by the 1979–1980<br />
committee were made.<br />
Following up on a 1973 subcommittee’s recommendation for a<br />
new income survey vehicle, the HEW Technical Working Group on<br />
income data and models proposed that a new survey be developed<br />
to provide better information on the income and related characteristics<br />
of the population and on participation in government programs.<br />
18 AMSTAT NEWS SEPTEMBER 2008<br />
<strong>Orshansky</strong> was a member of this group. The technical working group<br />
reviewed and contributed to the plan for what became the Income<br />
Survey Development Program—the research and development phase<br />
for the Survey of Income and Program Participation.<br />
In 1982, <strong>Orshansky</strong> retired from SSA after a government career<br />
that lasted for more than 40 years. She died on December 18, 2006,<br />
in New York City.<br />
<strong>Orshansky</strong> received a number of honors for her achievements.<br />
She received a Commissioner’s Citation from the Social Security<br />
Administration in 1965 for her creative research and analytical work<br />
and the Distinguished Service Award (the department’s highest recognition<br />
of civilian employees) from HEW in 1976 for her “leadership<br />
in creating the first nationally accepted measures of income adequacy<br />
and applying them diligently and skillfully to public policy.” In<br />
1974, she was elected a Fellow of the ASA for her leadership in the<br />
development of statistics for the measurement of poverty. After her<br />
retirement, she received a national award from the Children’s Defense<br />
Fund in 1989 and an Award for Distinguished Contribution from the<br />
<strong>American</strong> Political Science <strong>Association</strong> in 1993.<br />
<strong>Orshansky</strong>’s achievements also were recognized in a very different<br />
setting. She may be the only statistician to have been discussed on a<br />
major television show. One subplot of “The Indians in the Lobby,”<br />
an episode of “The West Wing” originally broadcast in November<br />
2001, involved the adoption of a new poverty measure, and one character<br />
alluded to how <strong>Orshansky</strong> developed the current poverty measure.<br />
While the discussion of issues relating to a new poverty measure<br />
sounded plausible, the episode grossly mischaracterized the rationale<br />
for <strong>Orshansky</strong>’s methodology for developing the poverty thresholds.<br />
Of the contributions to <strong>American</strong> public policy that <strong>Orshansky</strong><br />
made during her career, the greatest by far was her development of the<br />
poverty thresholds. The poverty line has become a major feature of<br />
the architecture of <strong>American</strong> social policy. Although the measure may<br />
have its shortcomings, the poverty line gives us a means of identifying<br />
and analyzing the makeup of the groups in our society with the least<br />
resources. <strong>Orshansky</strong>’s thoughtful analyses of the poverty population<br />
began a tradition, and there are now numerous researchers and advocates<br />
who conduct such analyses and draw policy implications from<br />
them. Even though there may not be consensus on answers, the question<br />
“How does it affect the poor?” has become a test for proposed<br />
policies and programs. And a simplified version of the poverty line is<br />
used to determine eligibility not only for certain federal programs, but<br />
for a number of state, local, and private programs, as well. ■

Life as a Stochastic Modeler<br />
Alan Gelfand, Duke University<br />
First, let me say I am flattered to be invited to write about my<br />
career in statistics. I do not know if many readers will find it<br />
interesting, but I do know it has evolved along a path that<br />
may be viewed as a reflection of the evolution of our field.<br />
What I have become is a stochastic modeler. In particular,<br />
a modeler whose primary focus is in the area of environmental<br />
processes, including ecological systems, exposure assessment, and<br />
climate processes. A common ingredient of this analysis is the collection<br />
of data across space and, often, across time. I am usually<br />
studying a complex process with different types of information—<br />
theoretical results drawn from physical principles, mechanistic<br />
insights based on knowledge of aspects of process function, and<br />
empirical knowledge as a result of previous data collection and<br />
relevant laboratory and field experiments.<br />
I imagine the process is described at multiple levels, with the<br />
foregoing information entering in at different places and levels.<br />
I typically represent the process through an acyclic-directed<br />
graph with some nodes observed and others unknown, and then<br />
I infer about the unknown nodes given the observed nodes. I<br />
formulate the joint model in a hierarchical fashion driven by<br />
the graph and fill in the stochastic details needed to complete<br />
the model specification. In essence, a stochastic modeler seeks<br />
the posterior distribution of what we don’t know given what we<br />
have observed, so we usually fit these graphical models within<br />
the Bayesian framework.<br />
It has emerged, more clearly than ever, that such modeling is<br />
my greatest strength as a statistician. Moreover, being part of a<br />
team of researchers assembled to ‘brainstorm’ a complex problem<br />
is an exceptionally stimulating and rewarding activity. In<br />
this setting, the modeler becomes a central player in synthesizing<br />
inputs from team members, shaping progress on the problem,<br />
and becoming a richer scientist as a result.<br />
I think this research view serves as a contemporary perspective<br />
of our field. The team research concept, which it presumes, dramatically<br />
revises the role of the statistician from someone brought<br />
in at the end to carry out data analysis and create ‘pretty’ pictures.<br />
Rather, the statistician is able to illuminate what we can learn with<br />
what we have, as well as what we need to collect to learn about<br />
what we want. In the midst of all this, it is essential that the modeler<br />
retain technical rigor, attention to detail, and appreciation of<br />
the properties and features encompassed by the modeling.<br />
SEPTEMBER 2008 AMSTAT NEWS 21
How Did I Get Here?<br />
So, that is the story of what I do. But, how did I get here? I followed<br />
a fairly typical course for my time, starting as an undergraduate<br />
major in mathematics. In my senior year, I took an<br />
introduction to mathematical statistics course from the book by<br />
the same name written by Robert Hogg and Allen Craig (embarrassingly,<br />
using the first edition, spanning all of 240 pages). The<br />
material was so elegant, I was smitten, and I applied to graduate<br />
programs in statistics, moving to Stanford—as far from New<br />
York City as I could go.<br />
I thoroughly enjoyed my four years at Stanford. (The late<br />
1960s was a remarkable time for a statistics department in the<br />
San Francisco Bay area—and for the country.) I emerged with<br />
training as a mathematical statistician, really the only path available<br />
at that time. As I have told many people, I had a ‘wasted<br />
youth’ in some ways, not discovering until the late 1980s that I<br />
was born to be a Bayesian (and, with it, to be a modeler).<br />
People who influenced me include my adviser from Stanford,<br />
Herbert Solomon, a wonderful, generous man who was particularly<br />
good at recognizing how people could best contribute to<br />
projects. He was one of the earliest ‘team builders’ in our field.<br />
Charles Stein, who was also from Stanford, influenced me in<br />
a distant way. I believe I hold the record for the most courses<br />
ever taken from Stein by a single student. His beautiful, deep<br />
thoughts in decision theory led me down that research path,<br />
22 AMSTAT NEWS SEPTEMBER 2008<br />
which led me to empirical Bayes and, eventually, research within<br />
the Bayesian paradigm. Finally, Adrian Smith was most influential<br />
to me. Following conversations with him in the mid- to late<br />
’80s, I arranged a sabbatical to work with him at Nottingham<br />
University. I arrived seeking to use his numerical integration<br />
software for certain empirical Bayes problems and left with the<br />
Gibbs sampler!<br />
In this regard, I was fortunate to be involved in a seminal contribution<br />
to our field. Indeed, working with Smith, it was a remarkable<br />
feeling to come upon the Gibbs sampler from the 1984 paper<br />
of Stuart Geman and Donald Geman, “Stochastic Relaxation,<br />
Gibbs Distributions, and the Bayesian Restoration of Images,” and<br />
recognize it was better suited for handling Bayesian computation<br />
than it was for its original purpose—sampling Markov random<br />
fields. In fact, for the first half of the 1990s, I spent almost all<br />
my time writing as much about the use of Gibbs sampling and<br />
Markov chain Monte Carlo algorithms for Bayesian model fitting<br />
and model determination as I could. These were heady times for<br />
those of us involved, as we realized we were elaborating on a technology<br />
to successfully address the problem of Bayesian computation—to<br />
replace high-dimensional integration with simulation<br />
from high-dimensional distributions.<br />
In the mid 1990s, I started moving from research confined to<br />
computational matters to the analysis of spatial and spatial-temporal<br />
data. Again, I was fortunate. Spatial statistics had struggled as<br />
LATEX<br />

a field, functioning at the periphery of mainstream statistical<br />
work, and was particularly in need of inexpensive, high-speed<br />
computation to enable tools vital for visualization. Fortunately,<br />
this computing power arrived and, with it, the advent of geographic<br />
information systems (GIS) software to create effective<br />
maps that tell a broad range of stories. However, GIS software<br />
had an obvious limitation from a statistician’s perspective—it was<br />
descriptive, but not formally inferential. A wonderful opportunity<br />
for stochastic modeling revealed itself, an opportunity with<br />
few players at the time and a growing need in the applied community<br />
as more data with spatial content were being collected.<br />
Here, again, there was more good fortune for me, because<br />
advantages to hierarchical modeling for analyzing spatial data<br />
became evident—the advantages we attach to working in general<br />
in the Bayesian framework: fully model-based inference with<br />
accurate assessment of uncertainty. Additionally, the customary<br />
asymptotics, which are employed in time series, so-called expanding<br />
domain asymptotics, may be inappropriate for spatial data<br />
where infill asymptotics are perhaps more relevant. However,<br />
that the latter asymptotics typically reveal information about<br />
unknowns is bounded in terms of inference. In this regard, the<br />
Bayesian framework provides exact inference, avoiding possibly<br />
inappropriate asymptotics. Of course, the implied caveat is that<br />
the data never overwhelm the prior; we must be more attentive<br />
to prior sensitivity than in other areas.<br />
Today, my good fortune persists through continuing research<br />
relationships with talented former students. In particular,<br />
Sudipto Banerjee and Brad Carlin, both at the University of<br />
Minnesota, invaluably helped to shape my spatial data research<br />
agenda. During my career, I also found wonderful interdisciplinary<br />
collaborators. When I was at the University of Connecticut,<br />
I worked seriously at building bridges with ecology and evolutionary<br />
biology, yielding productive research relationships with<br />
John Silander and Kent Holsinger. Moving to Duke University<br />
made things even better, as Duke is a naturally collaborative<br />
institution; research teams develop over the campus with strong<br />
encouragement from the university. What program on campus<br />
is more naturally interdisciplinary than statistics? Now at Duke,<br />
I have productive relationships with researchers in the Nicholas<br />
School of the Environment, particularly Jim Clark and Marie<br />
Lynn Miranda.<br />
In summary, it seems my career has been one of ongoing good<br />
luck. To some extent, I believe this is true, but I also believe<br />
you can make your own luck. Scientific curiosity, receptivity to<br />
reading in other fields, availability for collaboration, willingness<br />
to listen, and attention to effective communication all facilitate<br />
creating opportunities. In addition, developing the full toolkit—<br />
strong theoretical training, stochastic modeling expertise, modern<br />
computing skills, and data analysis experience—enables one<br />
to take advantage of these opportunities. Some of us work better<br />
with certain parts of the toolkit and enjoy certain parts more<br />
than others; however, as statisticians in the 21st century, we can<br />
each find our own way to contribute and, in that sense, we are<br />
all fortunate. ■<br />

On Becoming a Teacher<br />
Daren Starnes, The Lawrenceville School<br />
As a fledgling mathematician, I was blessed to learn from several<br />
outstanding teachers. First and foremost, there was<br />
Sammi Yopp , my second-grade teacher at the North Carolina<br />
Charlotte Country Day School. Yopp sparked my mathematical<br />
curiosity and cajoled me into playing chess as a means of honing my<br />
analytic thinking skills. Several years later, my mathematical abilities<br />
were challenged by Sue Sams, my ninth-grade honors algebra II/<br />
trigonometry teacher at East Mecklenburg High School. Sams was,<br />
to put it mildly, a disciple of Mary P. Dolciani. The following year,<br />
I landed in the classroom of another Dolciani disciple, Roger<br />
Bruwhel at West Charlotte High School. Bruwhel was the one who<br />
encouraged me to leave my comfort zone by applying to the North<br />
Carolina School of Science and Mathematics (NCSSM). Off to<br />
NCSSM I went, where I was surrounded by a host of talented<br />
“mathletes,” budding scientists, and computer programmers. As a<br />
junior sitting in Dan Teague’s “Calculus with Topics” class one day,<br />
I made the decision to become a high-school math teacher. Why?<br />
Because I witnessed firsthand the tremendous passion, thirst for<br />
understanding, and knack for asking just the right question at the<br />
right moment that allows great teachers such as Teague to inspire<br />
students to do extraordinary things.<br />
From NCSSM, I went on to pursue a bachelor’s of science in<br />
mathematics with secondary teaching certification at the University<br />
of North Carolina, Charlotte (UNCC). At the time, UNCC was<br />
a teaching university, which enabled me to take all my classes with<br />
professors from the outset. At the urging of my professors, I participated<br />
in Budapest Semesters in Mathematics, where I fell in<br />
love with combinatorics and probability. Having never left the<br />
southern United States until that moment, I admit to experiencing<br />
a healthy dose of culture shock as a westerner in what was then<br />
socialist Budapest.<br />
From Eastern Europe, I accepted an offer to join a graduate<br />
program in pure mathematics at the University of Michigan. As I<br />
was nearing the end of my master’s degree requirements, it became<br />

”<br />
clear to me that my interests had shifted dramatically away from<br />
classical pure mathematics in the direction of research methods,<br />
combinatorics and graph theory, and statistics. Ironically, my only<br />
statistical coursework to that point was a calculus-based probability<br />
and statistics course as a sophomore at UNCC. Having reached an<br />
important fork in the road, I opted to end my relationship with<br />
pure math and begin my high-school teaching career.<br />
Charlotte Country Day School (CCDS) was my proving<br />
ground, the place where I learned the craft of teaching from supportive<br />
colleagues such as Tim Timson, Sheila McGrail, and Sue<br />
Schwartz. My interest in curriculum development blossomed.<br />
CCDS launched the International Baccalaureate (IB) program, and<br />
I volunteered to take on the IB Higher Level Math course. In my<br />
fifth year there, McGrail and I designed a course called “Probability,<br />
Statistics, and Finite Math” to better serve the needs of students<br />

Upcoming ENVR Workshop!<br />
What: <strong>Statistical</strong> Issues in Monitoring the Environment<br />
When: October 22–24, 2008<br />
Where: National Center for Atmospheric Research<br />
(NCAR), Boulder, Colorado<br />
This workshop covers state-of-the-art applications and<br />
statistical methods in environmental monitoring. Sessions<br />
on applications include monitoring in ecology, monitoring<br />
in air quality, monitoring of aquatic resources, and<br />
monitoring of climate change and its impacts. The spatio-temporal<br />
data collected in environmental monitoring<br />
present interesting and challenging statistical problems,<br />
such as modeling of space-time correlation, analysis<br />
of the huge amount of correlated data, and analysis of<br />
high-frequency monitoring data. Technical sessions will<br />
cover recent developments in statistical methods for environmental<br />
data. A one-day short course on the analysis of<br />
spatial and spatio-temporal data will be offered and taught<br />
by Doug Nychka. There also will be a poster session. Poster<br />
abstracts need to be submitted by September 23, 2008.<br />

who were not bound for AP Calculus. When AP Statistics kicked<br />
off in 1996–1997, I happily agreed to play a leadership role. Better<br />
still, CCDS science colleague Wright Robinson convinced me to<br />
team teach AP Statistics with AP Environmental Science, to collaborate<br />
on a field and lab manual, and to co-present at several<br />
conferences. Robinson got me started as a writer, having himself<br />
authored several children’s books about ecological topics. More<br />
than anything, Robinson convinced me to “get out there” as a contributing<br />
member of my profession.<br />
When our youngest son graduated from CCDS, my wife and<br />
I headed west to The Webb Schools in California to begin the<br />
next chapter in our lives. I assumed leadership of the mathematics<br />
department, and with the support of some exceptional colleagues,<br />
began to tweak the existing curriculum. We dissolved our existing<br />
geometry course and created an integrated geometry with algebra<br />
course that continues to evolve today. In addition, we added a capstone<br />
course for our most talented math students titled “Calculus-<br />
Based Probability and Statistics.”<br />
Externally, my role with the College Board expanded dramatically.<br />
I led four or five one-day workshops for AP Statistics teachers<br />
every year and a similar number of week-long summer institutes.<br />
These opportunities to help coach other teachers gave me a chance<br />
to share some of the lessons I learned in the trenches. At the same<br />
time, interacting with other highly motivated professionals encouraged<br />
me to further refine my own teaching.<br />
In the summer of 1998, I began reading AP Statistics exams.<br />
Every year since, I have attended this annual gathering of highschool<br />
and college/university statistics teachers, which some of us<br />
refer to fondly as “stats summer camp.” For the past eight years,<br />
I have been privileged to serve as part of the reading leadership<br />
team, first as a table leader and, more recently, as a question leader.<br />
Needless to say, reading hundreds of exam papers every day is not<br />
the highlight of the experience for most of us. Instead, it’s the tremendous<br />
opportunity to network with like-minded professionals<br />
who have amassed an abundance of content knowledge and a host<br />
of resources for teaching introductory statistics. There are abundant<br />
opportunities for discourse during breaks, at lunch, in the evening<br />
social lounge, and at various nightly professional events. Truth be<br />
told, some of my best conversations about statistics teaching have<br />
taken place at AAA baseball games.<br />
Shortly after my wife and I moved west, Dan Yates contacted<br />
me about assisting him with some of the calculator features in the<br />
second edition of The Practice of Statistics, the successful highschool<br />
AP Statistics textbook he coauthored with David Moore.<br />
Having spent three years co-editing the Technology Tips column in<br />
the National Council of Teachers of Mathematics’ (NCTM) magazine,<br />
Mathematics Teacher, I felt comfortable accepting this role as<br />
a minor contributor in the writing process. Somewhere along the<br />
way, I mentioned to Yates that I had a few suggested enhancements<br />
to the text based on my experiences as a user. To my surprise,<br />
he called my bluff and asked me to compose a revised version of<br />
Chapter 1 that incorporated my recommendations. Doing so took<br />
far longer than I had expected, with many false starts along the<br />
way. The net result of my efforts was a 120-page tome disguised<br />
as a single textbook chapter. With a typical dose of his southern<br />
charm, Yates quipped, “You know, if chapters were this long, we’d<br />
have to package the book with a wheelbarrow.” In the end, I was
instructed to “trim” the chapter to 60 pages. That was probably the<br />
most painful editing task I have ever undertaken! (There was one<br />
consolation: Nearly all the trimmed material ended up in a supplement<br />
somewhere.)<br />
So, my second career as a writer was launched. I teamed with Yates<br />
and Moore on a second venture—Statistics Through Applications, a<br />
high-school textbook for non–AP Statistics courses—that was completed<br />
in 2004. With both of my coauthors now retired, I’ll have my<br />
hands full with future revisions.<br />
In 2004, I was appointed to the ASA/NCTM Joint Committee<br />
on Curriculum in Statistics and Probability by then NCTM president<br />
Johnny Lott. Over the years, the joint committee has been responsible<br />
for several significant projects to develop materials that promote<br />
K–12 statistics education, including the Quantitative Literacy Series,<br />
the Elementary Quantitative Literacy Series, the Science Education<br />
and Quantitative Literacy Series, and Data-Driven Mathematics.<br />
The joint committee also has assumed responsibility for designing<br />
teacher workshops to support effective classroom use of these materials.<br />
With the ASA’s recent publication of Guidelines for Assessment and<br />
Instruction in Statistics Education (GAISE), the committee has begun<br />
developing materials and training to help teachers implement the curricular<br />
framework described therein. Roxy Peck and I just completed<br />
a capstone module for high-school students, titled “Making Sense of<br />
<strong>Statistical</strong> Studies,” which began as an ASA Member Initiative several<br />
years ago when Peck, Henry Kranendonk, and June Morita were<br />
members of the joint committee.<br />
DAY IN THE LIFE<br />
After a brief stint in independent school administration, I accepted<br />
an endowed chair position as Master Teacher in Mathematics at<br />
The Lawrenceville School this past fall. This unique position allows<br />
me to team teach with a different member of the department each<br />
trimester. By planning, instructing, and assessing collaboratively,<br />
we are able to improve our individual teaching practices. Our students<br />
also benefit from the distinct approaches and perspectives of<br />
their co-teachers. Other responsibilities as master teacher involve<br />
curriculum design, technology training, and professional development.<br />
Much of my time outside the classroom is spent in professional<br />
growth activities involving other teachers, either here at<br />
Lawrenceville or across the country at meetings, conferences, and<br />
workshops. Distilling that collective wisdom into better learning<br />
for students is at the heart of what I do on a daily basis.<br />
If I have become a teacher leader, it is because I have followed in<br />
the footsteps of the many great mentors and role models who have<br />
shaped my thinking. As my career has evolved, I have drifted from<br />
my origins as a pure mathematician into the realms of data analysis<br />
and statistics. All the while, my primary focus has remained squarely<br />
on how to help students learn mathematics (including statistics)<br />
in ways that will ensure their ability to use what they have learned<br />
to solve important problems today, tomorrow, and in the distant<br />
future. After all, if students see no potential to do anything productive<br />
with what they’re learning, why should they bother? ■<br />

What Does a Teaching<br />
Associate Professor Do?<br />
Pam Arroway, North Carolina State University<br />
For about a decade now, the Department of Statistics at North<br />
Carolina State University has been hiring faculty in career<br />
path, non-tenure-track teaching positions. These positions<br />
were first called clinical assistant professor positions, but have since<br />
been renamed teaching assistant professors. These positions are<br />
unusual in that they are not tenure-track, but they do have a career<br />
track, unlike instructor, lecturer, or adjunct positions found at<br />
many universities in the United States. Thus, a teaching assistant<br />
professor has the opportunity to be promoted to a teaching associate<br />
professor and a teaching professor. For simplicity, I’ll refer to a<br />
person in any of these positions as a TAP and to tenure-track or<br />
tenured faculty as TT faculty.<br />
What Do TAPs Do?<br />
Currently, the department has four TAPs, all of whom began at<br />
the assistant level and were promoted to the associate level. All<br />
currently have five-year contracts and PhDs in statistics or mathematics.<br />
Their responsibilities include a nominal teaching load of<br />
four courses per semester, though most TAPs begin with a “3+”<br />
contract. That is, the teaching load is three courses per semester,<br />
plus some scholarly activity. That may include research, but<br />
doesn’t have to.<br />
The four TAPs (including me) have evolved into very different<br />
roles within the department. The ways we contribute to the<br />
department, university, and profession include teaching graduate<br />
and undergraduate courses for statistics majors and as service<br />
courses; developing curricular and teaching materials to share<br />
with colleagues and/or publish; writing research papers; serving in<br />
administrative roles such as assistant department head, co-director<br />
of graduate programs, and director of undergraduate programs;<br />
recruiting, advising, and mentoring undergraduate and graduate<br />
students, including directing dissertation research; writing grant<br />
proposals; providing professional service by reviewing journal submissions;<br />
being an associate editor or grading AP Statistics exams;<br />
serving on committees… Sounds a lot like what a TT faculty member<br />
might do, right?<br />
So what does a TAP not do? In my department, there’s very little<br />
we can’t do. We have the opportunity to achieve our full potential.<br />
The biggest difference between a TAP and TT position is we allocate<br />
our time differently to the realms of teaching, research, and<br />
service. TAPs are not expected to publish in top statistical journals,<br />
advise a regular stream of graduate students, or get research grants,<br />
though we can do those things.<br />
We are expected to do a lot of outstanding teaching, and the<br />
flexibility of these positions has allowed us opportunities junior
Teacher Associate Professor (TAP) and Director of Undergraduate Programs Roger Woodard<br />
(center) mentors North Carolina State graduate students.<br />
faculty at a Research I university can rarely afford to consider. For<br />
example, we spend time on large course redesigns; organize conferences;<br />
develop teaching materials that are worth sharing and<br />
publishing; take on administrative roles; and go after grants for<br />
REUs, conferences, undergraduate and graduate support, enhancing<br />
diversity, and teaching activities.<br />
I want to note that a TAP is not the same as a TT person doing<br />
research in statistics education. We have recently hired someone in<br />
this type of TT position to begin in January 2009. She will have<br />
the same research, teaching, and service expectations as any other<br />
TT faculty, with her research focused on statistics education. A few<br />
other statistics departments have, or at least have advertised, similar<br />
positions. While some TAPs are active in the national statistics education<br />
community, there is not a requirement of education research<br />
for reappointment or promotion.<br />
Why Would Someone Want<br />
to Be a TAP?<br />
A TAP is typically someone who is passionate about teaching and<br />
mentoring students and who wants to be in a research-intensive<br />
environment. A TAP position may look similar to a TT position at<br />
an institution that places more emphasis on teaching and undergraduates.<br />
However, there are advantages to being in a Research I<br />
school and NC State, in particular.<br />
There are resources that may not be available at smaller institutions,<br />
such as for travel and professional development. In addition<br />
to supporting NC State’s well-established undergraduate program,<br />
we have opportunities to mentor graduate students in teaching,<br />
research, or in their graduate careers in one of the oldest, largest,<br />
and best graduate programs in the United States. In a large department,<br />
we have a variety of undergraduate and graduate classes to<br />
teach and are surrounded by colleagues with various expertise.<br />
Opportunities also exist to provide statistical consulting for students<br />
and postdoctoral fellows in other departments. We can have<br />

a big effect on the profession and in training critical thinkers. A<br />
variety of seminars (Bayesian, bioinformatics, biostatistics, environmental<br />
statistics, statistical genetics, regular departmental seminars,<br />
and seminars by a number of interview candidates) and special<br />
topics courses in the department and at the nearby <strong>Statistical</strong> and<br />
Applied Mathematical Sciences Institute provide opportunities for<br />
continuous professional development.<br />
Why Does the Department<br />
Want TAPs?<br />
The existence of TAPs at NC State does not mean TT faculty<br />
members are not excellent teachers. In fact, many have received<br />
university and national teaching awards. TAPs can make valuable<br />
contributions to the long-term goals of the department and the<br />

mission of the university. The creation of TAPs incorporates faculty<br />
members with different interests and skill sets and helps keep<br />
teaching loads for research-active faculty at a level where they can<br />
continue to be successful in their research productivity.<br />
Unlike short-term adjuncts or instructors, TAPs have a vested<br />
interest in the future of the department. So, while it is more of a<br />
commitment than hiring an instructor, the benefit to the department<br />
tends to be much greater. TAPs have the time for (and even<br />
expectation of) improving teaching and curriculum across the<br />
whole department. NC State TAPs have also taken on administrative<br />
and service roles that lessen the non-research workload of TT<br />
faculty, make use of the professional strengths of those in TAP<br />
positions, and contribute to the long-term growth of the department.<br />
TAPs also play an important role in training graduate students,<br />
especially for academic positions.<br />
And About That Pesky Tenure …<br />
I don’t miss it. Is my position less secure than my colleagues? My<br />
contract has to be renewed every five years. With reappointment,<br />
promotion, and post-tenure review every three to five years, I’m<br />
not sure TT faculty members have it any easier. The university,<br />
which regards us as “special ranks” faculty, has explicitly stated that<br />
the review process is the same for TAPs as for TT faculty, though<br />
contributions in different realms must obviously be weighted differently.<br />
Industry isn’t handing out five-year contracts either. Job<br />
security is not a bigger concern for me than for anyone else.<br />
Some professional organizations have been outspoken against<br />
increase in non-TT positions in academia. I agree that non-TT<br />
positions should not increase at the expense of TT positions. They<br />
should be used to complement TT faculty members and support<br />
the mission of the university. Universities must be ethical and<br />
respectful in how non-TT faculty members are treated. A TAP is<br />
not a person the department gets to abuse and then dump when<br />
funding gets tight. Neither are TAPs short-term, hired-as-needed<br />
teachers for low-level courses. In my department, the TAPs are very<br />
much respected by colleagues and the administration. We are not<br />
second-class citizens, and we participate in nearly all activities. For<br />
better or worse, we are expected to contribute as much as TT faculty,<br />
and we do in the realms of our passion and expertise. I love<br />
my job! (Okay, it is pay raise time, and I want my department head<br />
to count this as one of my publications.) ■

CAREER GUIDE<br />

Science, Duke University<br />
34 AMSTAT NEWS SEPTEMBER 2008<br />
This article is based on a talk I gave at the<br />
JSM 2007 meeting for the ASA Committee<br />
on Career Development. But, I should<br />
confess at the outset that I have no particular qualifications<br />
or any expertise on this topic, aside from<br />
having held a lot of jobs (which ought to raise<br />
questions about my suitability in the first place).<br />
Years ago, I was involved in drafting the New<br />
Researchers’ Survival Guide (available at www.<br />
imstat.org/publications). Reading over it again, we<br />
were awfully earnest and a bit naïve, but I think it<br />
has a lot of value for people who are beginning an<br />
academic career. So, I refer new faculty members<br />
to that, and, in this article, shall focus on topics<br />
that apply to everyone, not just recent PhDs and<br />
not just academics.<br />
Although statisticians are relatively homogeneous<br />
in our training, we have the usual range of<br />
talents, personalities, and utility functions. This<br />
creates many career paths and many ways to be<br />
successful. It also means you can be miserable if<br />
you get caught on a path that doesn’t fit your personal<br />
strengths and values.
All careers have a stochastic component, so<br />
we should look to dynamic programming as a<br />
model for continual reappraisal of our situations<br />
and ways that may better them. This implies a<br />
portfolio analysis perspective: We each have a<br />
different mix of strengths and weaknesses, and<br />
we should try to adaptively invest our energy in<br />
combinations that seem most likely to pay off.<br />
Some skills that apply to employment in all sectors<br />
are the following:<br />
Technical Strength. This is the<br />
foundation when you are starting out,<br />
but it often becomes less important as<br />
you advance. Especially in business and<br />
government, one needs breadth more<br />
than depth at the higher levels.<br />
Computational Ability. Anyone<br />
who can do solid statistical programming<br />
will never miss a meal. It is a blue<br />
chip skill and a way of thinking that has<br />
unique value. But, it is hard to become<br />
rich or famous on this alone.<br />
Public Speaking. Every member of<br />
the ASA has survived at least 1.5 decades<br />
of dull lectures in school, which is why it<br />
amazes me that so many of us have not<br />
learned enough from that experience to<br />
avoid giving bad talks. Good presentations<br />
are a key component of almost any success<br />
story, and whatever you can do to<br />
build strength in this area will repay your<br />
efforts. If English is not your native language,<br />
that can be an obstacle, but personality<br />
and style are much more important.<br />

Xiao-Li Meng of Harvard, whose native<br />
language is not English, give wonderful<br />
talks, and there are many others.<br />
Writing. It is crucial to be able to write<br />
clearly, correctly, and briefly. This is a<br />
lifelong learning process—anyone who<br />
writes well is constantly studying how to<br />
write and attending to their prose.<br />
Social Networking. This is crucially<br />
important, and it sometimes seems statisticians<br />
study it more, while learning less,<br />
than those in any other field. You need a<br />
diverse network; having a lot of friends<br />
who work on local asymptotic minimaxity<br />
is not as helpful as having friends with<br />

complementary strengths. In particular,<br />
bring your secretary flowers, talk to the<br />
system administrator about D&D, and<br />
go to a conference where there aren’t<br />
many statisticians.<br />
Organization. This sounds mundane,<br />
but it is very hard for a manager to promote<br />
you if you are sloppy or slow about<br />
paperwork. And the discipline of quick<br />
turnaround on such items (phone calls,<br />
emails, appointments, referee reports)<br />
helps in other aspects of one’s career.<br />
Time Management. When I was<br />
a young faculty member at Carnegie<br />
Mellon, Jay Kadane shared with me this<br />
advice: Carry a pocket diary and mark<br />
down everything you need to do. But, also<br />
realize everyone goofs off some (except<br />
maybe Peter Hall and David Dunson).<br />
So, don’t waste time feeling guilty about<br />
wasting time—just be efficient when you<br />
actually get down to work.<br />
Someone else would probably generate a<br />
slightly different list, but these are all key areas<br />
to cultivate.<br />
One situation where many people damage<br />
their careers is at internal business meetings.<br />
Always be concise. Try to read the interpersonal<br />
dynamics—you need to hear the subtext,<br />
read the body language, and notice what<br />
doesn’t get said. Do not pursue pet projects or<br />
raise dead issues—the way to lobby for those is<br />
through one-on-one talks, and it can be a slow<br />
process to build support.<br />
When I joined the National Institute of<br />
Standards and Technology, Lynne Hare advised<br />
me to “avoid other people’s nonsense.” Help keep<br />
meetings focused; people loathe those who, often<br />
unconsciously and with benign intent, hijack a<br />
meeting. Probably no constructive meeting lasts<br />
more than 50 minutes, and no participant can<br />
make more than one key point per meeting (but<br />
you should generally try to make a point, just to<br />
prove you are relevant). Except when brainstorming<br />
over beer, you should never think out loud,<br />
unless you are the smartest person in the room, and<br />
even then it is perilous. A good rule of thumb for a<br />
meeting is to pretend you are one of the characters<br />
on the television show “West Wing.”<br />
Most of us will hold many jobs. Our chief assets<br />
are reputation, capability, and social capital—not<br />
seniority. So, when one moves on, try to leave only<br />
friends behind—it isn’t always easy, as changing jobs<br />
is usually prompted by dissatisfaction, but, after a<br />
few years, things will seem less intense. My sense is<br />
that no organization is more than two bad managers<br />
(in time or hierarchy) away from meltdown, so<br />
it is good to have an exit plan. And, each time you<br />
change jobs, you get the chance to learn new skills<br />
and make new friends; most of us can advance faster<br />
by moving than by staying. In terms of long-range<br />
planning, you need to think at least two moves<br />
ahead to achieve significant career growth, and you<br />
should choose those moves to ensure an ironclad<br />
résumé for the position you ultimately want.<br />
For those who need to stick in their job, there<br />
are still ways to advance. Personality counts for a<br />
lot. Try to pretend to be happy and productive.<br />
Read the newspaper so you have a wealth of conversation<br />
topics and aren’t stereotypically dull or<br />
narrow. You should avoid doomed projects, those<br />
that do not build new professional assets, and those<br />
for which you are not central. I’d recommend looking<br />
for projects that cross division boundaries—it<br />
helps to have a broad base of good opinion, and<br />
you can build unique collaborations the organization<br />
needs. When David Blackwell introduced<br />
Cuthbert Daniel to the Berkeley statistics department,<br />
he said “This man is worth 10 of us—not<br />
because he is better, but because he is different.”<br />
So, try to differentiate yourself. Think of at least<br />
one new idea a week, but be properly skeptical<br />
of its value.
Some people can climb high by sucking up.<br />
And this is not evil, nor is it uncouth if done<br />
with panache and a degree of dignity. It crosses<br />
a moral line (I think) if one takes advantage of<br />
such favoritism to torpedo others in the office.<br />
More broadly, statisticians may face special ethical<br />
challenges; we often have to find honest ways<br />
to let the data speak on behalf of our employers’<br />
interests, and sometimes that just isn’t possible. In<br />
such cases, you must use all your powers of diplomacy<br />
to head off direct conflict. But, if such arise,<br />
then doing the right thing is not going to protect<br />
you. So, keep an updated résumé handy and don’t<br />
wait around when the weather changes.<br />
The ASA was created to be an engine for career<br />
growth for all statisticians. Among its many other<br />
services, it offers the following:<br />
Salary surveys for statisticians, broken out<br />
by useful covariates such as sector and rank—<br />
this is essential for evaluating job offers and<br />
negotiating raises<br />
Professional job fairs at every JSM—the<br />
last day is open to all, and it never hurts to<br />
look at your options and keep your search<br />
skills sharp<br />
Continuing education opportunities, both<br />
as a student and as a teacher<br />
Sections, committees, and chapters that are<br />
ladders for leadership within the ASA, offer<br />
chances to network with like-minded people;<br />
and help build your résumé<br />
The opportunity to practice public speaking<br />
at every JSM and a 20-minute forum at which<br />
to advertise yourself<br />
Journals, a directory of members, online<br />
job listings, short courses, a conference<br />
calendar, and other ways to keep up with<br />
our profession and colleagues.<br />
These ASA resources are a huge benefit of<br />
membership, and their relative advantage is<br />
especially great for master’s statisticians, isolated<br />
statisticians, and those working in industries or<br />
agencies whose professional staff includes many<br />
nonstatisticians. ■<br />

Top Five<br />
Favorites<br />
We asked a few statisticians what<br />
their top five favorite statistical<br />
books were and why they chose<br />
them as important added components<br />
to their particular job. Here is<br />
what they had to say.<br />

�Barry Nussbaum<br />
Chief Statistician, U.S. Environmental<br />
Protection Agency<br />
1. The Cartoon Guide to Statistics by Larry<br />
Gonick and Woollcott Smith<br />
Despite its name (or, perhaps because of<br />
it), it is a good primer on statistics. Its<br />
catchy illustrations and succinct prose<br />
provide just the explanation of statistical<br />
concepts a statistician needs when describing<br />
some basic work to nonstatistician<br />
decisionmakers.<br />
The next three are classics in terms of<br />
established books, which display and<br />
explain statistical methodology.<br />
2. <strong>Statistical</strong> Methods by George Snedecor<br />
and William Cochran<br />
3. Applied Regression Analysis by Norman<br />
Draper and Harry Smith<br />
4. Nonparametric Statistics for the<br />
Behavioral Sciences by Sidney Siegel and<br />
N. John Castellan Jr.<br />
5. Finally, I rely on an old favorite: Darrell<br />
Huff’s How to Lie With Statistics. Far from<br />
being an instruction manual for statistical<br />
lies, it has a wealth of illustrations<br />
describing how statistics can be misused.<br />
Frequently, in complex analyses, we fail to<br />
realize we are making some of the mistakes<br />
Huff explains so well. So, I gladly use his<br />
examples to explain the fallacies we may<br />
be getting into.<br />

Director, Statistics Program,<br />
St. Olaf College<br />
1. Statistics: A Guide to the Unknown by<br />
Roxy Peck, George Casella, George Cobb,<br />
Roger Hoerl, and Deborah Nolan. I first<br />
became enthralled with this book many<br />
years ago when it was edited by Judith<br />
Tanur. In its current form, it is possible to<br />
find compelling, real-to-life examples for<br />
any level of cour se I am teaching.<br />
2. <strong>Statistical</strong> Sleuth by Fred Ramsey and<br />
Daniel Schafer—a difficult book for a<br />
first course for undergrads, but one we<br />
refer to often over the course of students’<br />
time here.<br />
3. Generalized Linear Models by P.<br />
McCullagh and J. A. Nelder provides a<br />
definitive, unified, treatment of methods<br />
for the analysis of diverse types of data.<br />
I realize the following two books do not<br />
exactly make for leisure time reading, but<br />
they come in handy as references.<br />
4. The R Book by Michael J. Crawley<br />
5. Handbook for Statistics Using Stata by<br />
Sophia Rabe-Hesketh and Brian S. Everitt<br />
or A Handbook of <strong>Statistical</strong> Analyses Using<br />

A re You Media Shy…<br />
Media Savvy?<br />
or<br />
While many of the people I’ve<br />
worked with would sooner have<br />
several teeth pulled than do a<br />
media interview, others take to the process<br />
like a duck to water. The basic difference<br />
between the two attitudes seems to be the<br />
individual’s confidence in his or her ability<br />
to control the interview. They would rather<br />
run the other way than get involved in a<br />
situation where they might be misquoted or<br />
misrepresented. The good news, however, is<br />
that every media-shy person can become<br />
media savvy with a little knowledge and<br />
practice. You can learn how to be more in<br />
control of an interview and to understand<br />
what the interviewer wants and needs.<br />
Sir Laurence Olivier attributed his success<br />
to two things: the confidence to perform<br />
and the humility to prepare.<br />
Six months ago, the ASA unveiled its<br />
Media Experts Program, and we have had<br />
good feedback from the media who have<br />
used it. Some of our experts have had a<br />
great deal of media experience, and I asked<br />
them for their best advice on doing media<br />
interviews. Some of their comments are<br />
CAREER GUIDE<br />

ASA Public Relations Specialist<br />
quoted below, while others are incorporated<br />
into the text. One of the journalists who<br />
uses our experts list fairly frequently is Carl<br />
Bialik, The Wall Street Journal’s Numbers<br />
Guy. I asked Bialik what he was looking for<br />
when he spoke with an expert and included<br />
his answers in the sections below. Bialik also<br />
said he wanted an expert willing to give<br />
an overall assessment of the statistical relationship<br />
or statistical techniques used in a<br />
paper he’s covering, rather than addressing<br />
a few minor quibbles … the big picture, so<br />
to speak. In general, this is a good point to<br />
remember for every interview.<br />
Below are some guidelines to help you<br />
become a media savvy interviewee.<br />
Respect deadlines, but buy<br />
some time to think.<br />
The first point on Bialik’s list of what he<br />
looks for when he speaks to an expert is<br />
“awareness of the importance of deadlines.”<br />
That said, however, if you’re asked to do an<br />
interview, buy a little time. Ask what the<br />
editor/writer wants to discuss, and don’t<br />
do the interview until you can think about<br />
SEPTEMBER 2008 AMSTAT NEWS 43
44 AMSTAT NEWS SEPTEMBER 2008<br />
what you’re going<br />
to say. <strong>News</strong> people<br />
almost always work<br />
on deadlines of a few<br />
hours to a few days, but<br />
that doesn’t mean you have<br />
to jump in without knowing<br />
what will be discussed. If you<br />
tell the journalist you’re in the<br />
middle of something and can talk<br />
to them in 15 or 30 minutes, you are<br />
respecting their need for speed, and<br />
those few minutes will give you time<br />
to think about the topic before you start<br />
answering questions. If they have a longer<br />
lead time, usually they will be happy to<br />
schedule a time to talk later.<br />
“Make sure you understand what is<br />
being asked, and that you can contribute<br />
something sensible on the point,” advised<br />
David Peterson, who is semi-retired and<br />
formerly of the Duke statistics faculty.<br />
Remember that you may<br />
be talking to someone<br />
with little or no knowledge<br />
of statistics.<br />
There are basically two types of news people:<br />
generalists and specialists. The generalists<br />
are not subject-matter experts; they<br />
may cover a strike in the morning, an auto<br />
accident in the afternoon, and a program<br />
on nuclear fusion in the evening. Some<br />
science writers have a lot of science background.<br />
In both cases, however, you may<br />
be dealing with people who know little or<br />
nothing about statistics. Don’t overestimate<br />
the interviewer’s expertise; you may need to<br />
provide enough background about a subject<br />
so you can lead the interviewer to ask<br />
the right questions. As one journalist once<br />
aptly put it, “If I don’t ask the right question,<br />
make sure you give the right answer.”<br />
“If a reporter’s question is unclear or not<br />
posed in such a way that one can answer it<br />
usefully, the most valuable thing one can do<br />
is to first provide some background explanation<br />
to help them understand the issues.<br />
That is, lead the reporter to ask the right<br />
question, then answer it,” said Peter F. Thall<br />
of the M. D. Anderson Cancer Center.<br />
Keep it simple<br />
All our media experts agree you have to<br />
speak in plain English and not use technical<br />
jargon in interviews. You need to be as<br />
accurate and complete as possible in your<br />
answers, but you shouldn’t go into so much<br />
detail that the answer becomes confusing.<br />
Using language your interviewer doesn’t<br />
quite understand is one of the major reasons<br />
experts are misquoted. The more technical<br />
you are, the more likely you are to be<br />
misunderstood and/or misquoted.<br />
“Avoid statistical jargon. The audience<br />
won’t understand and may, in fact, take<br />
a different meaning from your intended<br />
message.” This is sound advice from<br />
C. Shane Reese of Brigham Young<br />
University.<br />
Know your audience<br />
Yes, you’re talking to a journalist, but you’re<br />
really talking to his audience. Framing<br />
your answers for the journalist’s audience is<br />
really the key to giving a good interview.<br />
That’s also the key to getting your comments<br />
used—the more relevant they are<br />
to the interviewer’s audience, and the better<br />
you are at explaining things succinctly,<br />
the more likely you are to be quoted—and<br />
quoted correctly. So, if you’re not familiar<br />
with the news outlet, ask who makes up the<br />
audience. Journalists use their audience to<br />
filter what you say: What is the implication<br />
of the particular topic to the audience?<br />
Does it mean an additional congressional<br />
district in their state? More money for a
school district? Better health<br />
care? If you cannot make your<br />
comments relevant to the audience,<br />
they won’t get used.<br />
Jessica Utts of the University of<br />
California-Davis, said she tries to “translate<br />
technical information into something the<br />
public can understand.”<br />
Use examples to clarify<br />
and explain.<br />
Our media experts have varying opinions<br />
about using examples or analogies in interviews,<br />
although most of them voted a qualified<br />
yes to the use of these tools. Some said<br />
the wrong example can seem to trivialize an<br />
issue that isn’t trivial, while others feel talking<br />
to the journalist’s audience is not much different<br />
than teaching statistics to nonstatistics<br />
majors. While journalists welcome the kinds<br />
of examples that help illustrate a difficult<br />
point, you probably have to use your judgment<br />
in each case. According to Bialik, he<br />
wants experts he interviews to have “the ability<br />
to put their findings in terms accessible<br />
to a general audience, including providing<br />
analogies and examples.”<br />
“Yes, it is helpful to use an example,<br />
which can clarify how the statistical issue/<br />
result is directly relevant to people’s lives,”<br />
said David Dunson of the National Institute<br />
of Environmental Health Sciences. “It makes<br />
things more concrete.”<br />
If you don’t know, say so.<br />
If the topic of the interview is out of the<br />
scope of your experience or responsibility,<br />
your best bet is to politely decline and, if<br />
possible, direct the writer to someone who<br />
may be able to help. Once you’re into the<br />
interview, don’t speculate or talk beyond<br />
your expertise, and remember that opinions<br />
are not facts. Some journalists will try to get<br />
you to answer a question even if you don’t<br />
feel qualified, but the majority of good journalists<br />
will accept your refusal to answer. In<br />
fact, Bialik cited the following as a desirable<br />
quality in an expert: “Honesty when they<br />
can’t speak with expertise about the issue”<br />
being addressed.<br />
“If you’re asked a question to which you<br />
do not know the answer, don’t be afraid to say<br />
so,” advised Susan Ellenberg of the University<br />
of Pennsylvania School of Medicine. “No<br />
one is expected to know everything.”<br />
Don’t say anything you don’t want to see<br />
in print or on the 6 p.m. news, and don’t let<br />
interviewers put words in your mouth.<br />
You can’t control the interviewer’s questions,<br />
so focus on controlling your answers.<br />
Anything you say in an interview can be<br />
quoted, even if it originated with the interviewer.<br />
For example, a journalist may ask<br />
you if you have problems with the methodology<br />
used in a study. If you repeat what<br />
was said, or even deny it, you can be quoted<br />
as talking about questionable methodology.<br />
Instead, answer the question by making a<br />
positive statement about the study or some<br />
aspect of it. Additionally, it’s important to<br />
remember that the interview is not over until<br />
it’s over—until the phone is hung up, the<br />
cameras or mikes are off, or you’ve left the<br />
building. You have to be disciplined enough<br />
to not get pulled into discussion after the<br />
fact because it could become the story.<br />
“If you wouldn’t write it and sign it,<br />
don’t say it,” said Earl Wilson, former Red<br />
Sox pitcher.<br />
CAREER GUIDE<br />
Anything that can<br />
go wrong might.<br />
Finally, it’s important to know things can<br />
go wrong no matter how good a job you<br />
do. The story could turn out to be unfair<br />
or inaccurate. If it does, bite the bullet<br />
and don’t call the journalist or editor to<br />
complain. It’s a bad idea to get into an<br />
argument with someone who buys ink<br />
by the barrel or videotape by the mile.<br />
Once the journalist files her story, it<br />
goes into the system, to the editor, the<br />
copy editor, and so on. Any of those<br />
folks can change the story without<br />
checking with the journalist. The headline<br />
writer can change the whole focus<br />
of a story with the headline he writes,<br />
or the producer can cut the story and<br />
change its meaning.<br />
Bottom line: There are no guarantees,<br />
but your best chance of having a<br />
good outcome is to be prepared and follow<br />
the guidelines above. Good luck! ■<br />

Up-and-Coming<br />
Statisticians on<br />
the Verge of<br />
Great T hings<br />
Statisticians work in so many fields—<br />
from animal health to ecology to<br />
agriculture to computer science—<br />
and, every year, an untold number make a<br />
name for themselves. <strong>Amstat</strong> <strong>News</strong> asked<br />
around, and the names of the statisticians<br />
below just kept coming up as those belonging<br />
to people on the verge of doing great<br />
things. Allow us to introduce some of the<br />
ASA’s up-and-coming statisticians.
Name a statistician you admire and<br />
tell us why.<br />
If I’m supposed to name a historical figure here,<br />
I would pick Fisher, but the most honest answer<br />
would have to be my advisor, Peter Bickel. Not<br />
only because of his work, but because of the great<br />
positive influence he’s had on so many people’s<br />
lives and careers.<br />
What do you love most about<br />
your profession?<br />
When something you’ve been struggling with<br />
finally works, be it a proof or a piece of code.<br />
When you are collaborating with someone and<br />
know that, together, you are doing work neither<br />
of you could have produced on your own. When<br />
a student just understood something you’ve been<br />
explaining and you can see it’s a fascinating revelation<br />
for them. Of course, all these things are not<br />
unique to statistics. As for statistics, itself, the fact<br />
that almost everyone needs it is a nice bonus.<br />

Berkeley (PhD 2002)<br />
Research Interests:<br />
Liza Levina’s interests center on inference for high-dimensional<br />
data, including large p small n problems, covariance estimation,<br />
dimension reduction, and networks.<br />
What do you hate most about<br />
your profession?<br />
The same things that everyone else does—papers<br />
getting rejected, particularly by incompetent referees.<br />
Dealing with bureaucracy. The time pressure<br />
of tenure track. Also, that every doctor and<br />
nurse I’ve ever met felt obliged to tell me how<br />
much they hated statistics in college.<br />
What was the best career advice you<br />
were given?<br />
Co-advising graduate students. We have all had<br />
conversations with colleagues that end in “we<br />
should really talk more about this,” and then<br />
nothing happens because no one has time. But,<br />
if you get a joint student, then the collaboration<br />
really will happen.<br />
What is one web site/blog you can’t<br />
go a day without visiting?<br />
None. After my daughter was born (she’s almost<br />
three now), my free time has become much too<br />
scarce to spend it on reading blogs.<br />
What is something your friends<br />
would be surprised to learn about you?<br />

Age: 42<br />
Title: Biostatistician<br />
Employer: USDA<br />
Agricultural Research<br />
Service<br />
Alma Mater: University<br />
of Louisiana at Lafayette<br />
What are your research interests?<br />
The research I do involves statistical and epidemiologic<br />
approaches to identify relationships among<br />
dietary, physiological, genetic, and behavioral characteristics<br />
that may be associated with overweight or<br />
obesity in humans.<br />
Name a statistician you admire and<br />
tell us why.<br />
The name of a statistician that I admire is Don<br />
Mercante, who is the director of the biostatistics<br />
program at the LSUHSC School of Public Health in<br />
New Orleans. While Don is not a ‘famous’ statistician,<br />
he helped me out tremendously when I started<br />
my first job as a statistician. I knew I could always<br />
go to Don for help with a statistical issue, or even a<br />
professional issue. He was (is) truly a great mentor—<br />
always giving good advice and making time for you,<br />
no matter how busy he happens to be.<br />
What do you love most about<br />
your profession?<br />
What I love most about the statistical profession is<br />
the wide variety of scientific disciplines to which<br />
I am exposed. My first love was biology, so I truly<br />
enjoy seeing the relevance of statistics in biological<br />
fields, especially nutrition and medicine.<br />
What do you hate most about<br />
your profession?<br />
What I dislike most about the statistical profession<br />
is the degree of mistrust and suspicion investigators<br />
from other fields hold for statistics. I believe this simply<br />
results from a lack of understanding of statistics<br />
and the bad press to which statistics is sometimes<br />
subjected.<br />
What is the best career advice you<br />
were given?<br />
The best career advice I was given actually came<br />
from my brother, who is an electrical engineer. He<br />
told me to never sell myself short and to view a job<br />
interview as a two-way street. That is, I should interview<br />
the prospective employer as much as he/she is<br />
interviewing me.<br />
What is one web site/blog you<br />
can’t go a day without visiting?<br />
This is going to sound so nerdy, but one web site I<br />
cannot go a day without visiting is the SAS documentation<br />
web site that contains documentation<br />
for all their procedures. I am constantly learning<br />
(or relearning) the theory behind statistical methods<br />
simply by reading the documentation provided<br />
to correctly use these procedures. It’s such a great<br />
resource for me.<br />
What is something your friends would be<br />
surprised to learn about you?<br />
Something my friends might be surprised to learn<br />
about me is that mathematics did not always come<br />
easily to me. In fact, it was often the subject I struggled<br />
with the most in high school and college.
Research Interests:<br />
The focus of my research is on<br />
graphical models and algebraic<br />
statistics. Graphical models are<br />
multivariate statistical models<br />
in which observed variables<br />
are constrained to exhibit<br />
dependence patterns associated<br />
with a graph. My work in<br />
algebraic statistics is primarily<br />
concerned with statistical<br />
inference in models that have<br />
parameter spaces with algebraic<br />
structure. Many graphical<br />
models are, in fact, of this<br />
algebraic type.<br />

Name a statistician you admire and<br />
tell us why.<br />
Looking beyond the circle of my doctoral and postdoctoral<br />
advisors but keeping within my areas of<br />
interest, the name Steffen Lauritzen immediately<br />
comes to my mind. He has done groundbreaking<br />
work on graphical models, and his book is the standard<br />
reference in this area. Over the past few years,<br />
I have had several opportunities to be at meetings<br />
organized or attended by Steffen and, over and over<br />
again, I am impressed by his quick thinking and his<br />
truly constructive comments on the various speakers’<br />
presentations. I also admire Steffen’s supportive<br />
nature and positive attitude toward younger faculty.<br />
He is always encouraging, and I have never<br />
seen him pass on judgmental views. I think I am<br />
not alone in having benefited and drawn motivation<br />
from his suggestions.<br />
What do you love most about<br />
your profession?<br />
Academic statistics is a small field when judged by<br />
a headcount, but it is incredibly diverse. Research<br />
may address purely mathematical questions, solve<br />
algorithmic and computational problems, or be<br />
concerned with applied questions. Each one of these<br />
three areas is challenging in its own way, and I very<br />
much enjoy the exchange of ideas and problems<br />
between the three camps of mathematical, computational,<br />
and applied statistics.<br />
What do you hate most about<br />
your profession?<br />
I really dislike turf wars between mathematically<br />
minded and applied statisticians about who does<br />
‘good’ or ‘important’ research. I consider myself very<br />
fortunate to be part of the department at Chicago,<br />
where we have a very collegial atmosphere. Also, I do<br />
not generally enjoy people pushing dogmatic views<br />
on the different approaches to statistical inference.<br />
What is the best career advice you<br />
were given?<br />
I have been guided by a number of excellent advisors.<br />
When enrolled in an applied mathematics program<br />
back in Germany, it was Friedrich Pukelsheim who<br />
first brought my attention to statistics. During my<br />
PhD studies in Seattle, I received a lot of guidance<br />
from my advisors, Thomas Richardson and Michael<br />
Perlman. It was through Thomas that I met Bernd<br />
Sturmfels, whose advice to spend a year at Berkeley<br />
as a postdoc was probably the most influential professional<br />
advice I have received. Based on my experience,<br />
I would recommend doing a postdoc to any<br />
fresh PhD. It is a great way to finish off thesis papers<br />
and explore new avenues for research.<br />
What is one web site/blog you<br />
can’t go a day without visiting?<br />
After checking an old email account, I usually take<br />
a look at http://de.yahoo.com to pick up some news<br />
about Germany. I probably use the site mostly to<br />
read up on sports news. They also have a lot of livetickers<br />
for soccer games and, of course, they always<br />
cover my favorite club: FC Bayern Munich.<br />
What is something your friends would be<br />
surprised to learn about you?<br />
I am not sure there is anything I could do to surprise<br />
my friends. So, I will try to surprise some strangers<br />
by sharing two pieces of trivia:<br />
I have been playing soccer since I was a little<br />
kid and, naturally, I racked up a number of injuries.<br />
Sitting at a desk most of the day doesn’t help<br />
with keeping in shape, and so the frequency of<br />
injuries has increased over the last 7–8 years. In<br />
fact, I am currently working from home while<br />
recovering from my fourth knee surgery. For several<br />
years, someone’s Achilles tendon has been<br />
playing ACL in my left knee, and, since two<br />
weeks ago, someone’s patella tendon serves as the<br />
ACL in my right knee.<br />
The second piece of trivia involves a prize. Very<br />
few will find it surprising that pronouncing my last<br />
name is a very painful task in virtually all of this planet’s<br />
languages. However, some may find it surprising<br />
that outside the circle of my (great-)grandparents,<br />
parents, and three sisters, I have never met anyone<br />
with my last name. This makes me wonder whether<br />
I am the world’s only male heir to this concatenation<br />
of mostly consonants. For possible resolution of this<br />
matter, I would like to offer a pint of beer at the next<br />
Joint <strong>Statistical</strong> Meetings to the first few people who<br />
know/have heard of a person with last name Drton<br />
who is not related to me.<br />

R. A. Fisher, who proposed and developed many<br />

Statistics Is Literature<br />
Almost 30 years ago, something happened<br />
that made introductory statistics harder to<br />
teach. Students didn’t suddenly become less<br />
teachable, nor did professors forget their craft. It was<br />
that we began to switch from teaching statistics as a<br />
mathematics course to teaching the art and craft of<br />
statistics as its own discipline. When statistics was<br />
viewed as a subspecialty of mathematics, students<br />
were taught to manipulate formulas and calculate<br />
the ‘correct’ answer to rote exercises. Life for the<br />
teacher, both as instructor and grader, was easy.<br />
That started changing in the early 1980s. The<br />
video series “Against All Odds” appeared, and David<br />
Moore and George McCabe published Introduction<br />
to the Practice of Statistics. Since then, two pioneering<br />
committees—one for the Mathematical <strong>Association</strong><br />
of America and the ASA and one for the National<br />
Council of Teachers of Mathematics and the ASA<br />
that produced the Guidelines for Assessment and<br />
Instruction in Statistics Education (GAISE) Report—<br />
have pushed us all to change our teaching. And a<br />
new generation of texts has appeared following the<br />
advice of these reports, challenging statistics teachers<br />
to use this new approach.<br />
But why is it more difficult to teach this way?<br />
And why is it so important that we do?<br />
By comparison, let’s look at mathematics. Much<br />
of the beauty of mathematics stems from its axiomatic<br />
structure and logical development. That same<br />
structure facilitates—in fact dictates—the order<br />
in which the material is taught. It also ensures the<br />
course is self-contained, so there are no surprises.<br />
But, modern statistics courses are not like that, and<br />
that can frustrate students who were expecting a
math class. As a student of one of us once wrote on<br />
the course evaluation form, “This course should be<br />
more like a math course, with everything you need<br />
laid out beforehand.”<br />
Mathematics has a long history of prodigies and<br />
geniuses, with many of the most famous luminaries<br />
showing their genius at remarkably early ages.<br />
We’ve all heard at least one version of the famous<br />
story of young Carl Friedrich Gauss. A web search<br />
finds more than 100 retellings of the story, but<br />
an article by Brian Hayes in <strong>American</strong> Scientist’s<br />
“Gauss’s Day of Reckoning” identifies a version<br />
actually recounted at Gauss’ funeral. In that version,<br />
Gauss—age 7 and the youngest in the class—<br />
summed the numbers from 1 to 100 in seconds,<br />
wrote the answer on his slate, and then threw it<br />
down on the table mumbling “there it lies” in the<br />
local dialect. It was perhaps an hour later that the<br />
teacher discovered that his answer was, in fact, the<br />
only correct one in the room.<br />
Prodigies in math can develop at remarkably<br />
early ages because math creates its own self-consistent<br />
and isolated world. Pascal had worked out<br />
the first 23 propositions of Euclid by age 12 when<br />
his parents, who wanted him to concentrate on<br />
religion, finally relented and presented him with a<br />
copy of Euclid’s Elements. Galois wrote down the<br />
essentials of what later became Galois Theory the<br />
night before a fateful duel when he was 20, or so the<br />
legend has it. In the modern era, Norbert Weiner<br />
entered Tufts at age 11; Charles Pfefferman of<br />
Princeton was, at 22, the youngest full professor in<br />
<strong>American</strong> history; and Ruth Lawrence of Hebrew<br />
University passed her A-levels in pure math at age<br />
9 and became the youngest student ever to enroll at<br />
Oxford two years later.<br />
Of course, mathematics isn’t the only field<br />
that shows prodigies. Mozart, Schumann, and<br />
Mendelssohn, among others, were young musical<br />
prodigies. Even though his music matured, it is<br />
remarkable that some of the music Mozart wrote at<br />
age 5 is still in the repertoire.<br />
Also, chess prodigies continue to appear.<br />
Sergey Karjakin is the youngest grandmaster ever<br />
at 12 years, 7 months. The infamous late Bobby<br />
Fischer—who was youngest in 1958 when he<br />
became a grand master at 15 years, 6 months, and<br />
1 day—is now only 19th on that list.<br />
But there are only a few fields that develop<br />
prodigies, and all seem to be self-contained. For<br />
example, as professor of English at the University<br />
of Connecticut, Thomas Dulack observed, “There<br />
are no child prodigies in literature.” Although one<br />
might argue that William Cullen Bryant, Thomas<br />
Chatterton, H. P. Lovecraft, or Mattie Stepanek<br />
qualifies as a literary prodigy, that list doesn’t have<br />
quite the same panache as the others we’ve cited. It’s<br />
no easier to find prodigies in art, poetry, philosophy,<br />
or other endeavors that require life experience.<br />
What does any of this have to do with statistics<br />
and how can it help us understand why introductory<br />
statistics is so hard to teach? The challenge for<br />
the student (and teacher) of introductory statistics<br />
is that, as literature and art, navigating through<br />
and making sense of it requires not just rules and<br />
axioms, but life experience and “common sense.”<br />
Although working with elementary statistics<br />
requires some mathematical skills, we ask so much<br />
more of the intro stats student than is required by,<br />
for example, a student in his or her first calculus<br />
course. A student in calculus I is not asked to comment<br />
on whether a question makes sense, whether<br />
the assumptions are satisfied (e.g., Is the reservoir<br />
from which the water pouring really a cone?), to<br />
evaluate the consequences of the result, or to write<br />
a sentence or two to communicate the answer to<br />
others. But, that’s exactly what the modern intro<br />
stats course demands.<br />
The challenge we face is that, unlike calculus I,<br />
we have a wide variety of skills to teach, and most of<br />
them require judgment in addition to mathematical<br />
manipulation. Judgment is best taught by example<br />
and experience, which takes time. But, we’re supposed<br />
to produce a student capable of these skills<br />
in one term. It would be challenging enough<br />
to teach the definitions, formulas, and skills<br />
in the standard first course. To convey in<br />
addition the grounds for sound judgment<br />
is even more difficult. It should<br />
be no wonder that the first course in<br />
statistics is widely acknowledged to<br />
be one of the most difficult courses<br />
to teach in the university.<br />
It is not merely that we hope to<br />
teach judgment to sophomores; we<br />
are actually asking our students to<br />
change the way they reason about<br />

the knowledge to act
the real world. P. F. Velleman in his 2003 keynote<br />
address to the Beyond the Formula conference<br />
called the skills they must acquire the<br />
seven unnatural acts of statistical thinking:<br />
➊<br />
➋<br />
Think critically.<br />
Challenge the data’s credentials; look<br />
for biases and lurking variables.<br />
Be skeptical.<br />
Question authority and the current<br />
theory. (Well, okay, sophomores do<br />
find this natural.)<br />
➌ Think about variation, rather than<br />
about center.<br />
➍<br />
➎<br />
Focus on what we don’t know.<br />
For example, a confidence interval<br />
exhibits how much we don’t know<br />
about the parameter.<br />
Perfect the process.<br />
Our best conclusion is often a refined<br />
question, but that means a student<br />
can’t memorize the ‘answer.’<br />
➏ Think about conditional<br />
probabilities and rare events.<br />
Humans just don’t do this well. Ask<br />
any gambler. But, without this, the<br />
student can’t understand a p-value.<br />
Embrace vague concepts. Symmetry, center,<br />
outlier, linear … the list of concepts fundamental<br />
to statistics but left without firm definitions<br />
is quite long. What diligent student wanting to<br />
learn the ‘right answer’ wouldn’t be dismayed?<br />
How can we help students navigate these<br />
woods? We don’t have definitive answers to the<br />
question, in spite of our more than 50 years<br />
(combined) teaching of introductory statistics.<br />
But, we’d like to identify some themes that<br />
might help us as a community to start a conversation<br />
about some of the challenges.<br />
We can help students by giving them a<br />
structure for problemsolving that incorporates<br />
the requirement that they exercise their<br />
judgment. In our books, we’ve recommended<br />
that students follow the steps W. E. Deming<br />
created more than 50 years ago in his advice<br />
to industry: plan, do, check, act. We’ve substituted<br />
communicate for act to underscore<br />
the importance of communicating to others<br />
the results we see. Students must learn to<br />
communicate their results in plain language, not<br />
only in statistical jargon.<br />
As GAISE emphasized, we must place more<br />
emphasis on the plan and communicate steps. The<br />
emphasis of the traditional mathematical course,<br />
on the do step can be largely replaced by relying<br />
on technology for the calculations and graphics.<br />
In teaching students to think through the problem,<br />
plan their attack, and communicate results,<br />
we bring students face-to-face with their real-world<br />
knowledge and experience—with the literature<br />
side of their maturing intellect. We owe them an<br />
acknowledgement that we’ve done this. It isn’t fair<br />
to emphasize the simplicity of the calculations or to<br />
just provide a bunch of definitions in little boxes.<br />
No comparative literature or philosophy teacher<br />
would do that, and neither should we.<br />
What guidance should we offer? First, we can<br />
note that the judgment often called for in statistics<br />
is one that invites students to state their personal<br />
views. (After all, they are the ones who must be<br />
95% confident in their interval.) But, we can offer<br />
guidance for their judgments; they must be guided<br />
by the ethical goal of discovering, describing, modeling,<br />
and understanding truth about the world.<br />
Second, we can remind students their introductory<br />
statistics course is related to every other course<br />

they may study. The reason they are taking statistics<br />
(or perhaps, the reason it’s required) is that they<br />
are accumulating the kind of knowledge about the<br />
real world that will help them write literature and<br />
read philosophy, and that kind of knowledge makes<br />
them qualified to make statistical judgments. Of<br />
course, by asking students to call upon what they’ve<br />
learned in other courses, we are encouraging them<br />
to solidify their knowledge from those courses.<br />
Third, we must actually require students to<br />
demonstrate all the steps of a statistical analysis,<br />
from problem formulation to communicating the<br />
results to making real-world recommendations on<br />
what they find. Unfortunately, homework and<br />
exam problems that carry these requirements are<br />
harder to write and harder to grade. Training teaching<br />
assistants to reliably grade these efforts can be<br />
problematic. Moreover, many statistics instructors<br />
are not trained in statistics, and they, too, can find<br />
this approach challenging. But, the results of teaching<br />
a modern course reward both the student and<br />
teacher, in spite of its challenges.<br />
We should also face outward to the academic<br />
community. There is a widespread<br />
impression<br />
that introductory<br />
statistics can be taught—or even less plausible, can<br />
be learned—in a single term. Any objective consideration<br />
of the breadth and depth of the concepts<br />
and methods covered shows this to be absurdly<br />
optimistic. Yet, few academic programs require<br />
more than one course, and many of those that<br />
require two are cutting back. We need to argue as a<br />
discipline that an introductory statistics course must<br />
cover more than an introduction to inference for<br />
means if it is to teach the reasoning of statistics—<br />
and that teaching that reasoning must be its goal<br />
(not just teaching definitions and formulas.) But,<br />
a more complete course that covers techniques that<br />
require more than rudimentary sophistication, such<br />
as inference for regression and multiple regression,<br />
is unlikely to have time to teach judgment, planning,<br />
and communication. It will most likely be<br />
pared down to a collection of equations and rules.<br />
As a community, we need to make it clear that<br />
the subject of statistics deserves both more respect<br />
and more time, not because it covers so many<br />
methods, but because it should teach the foundations<br />
of reasoning when we have data. Part of the<br />
argument might be that, unlike students in subjects<br />
that exhibit prodigies, our students must summon<br />
their real-world knowledge to learn to think statistically.<br />
And, that the effort by statistics teachers and<br />
students will pay back correspondingly in all our<br />
students do. Math is sometimes said to be the language<br />
of science (and much social science), but statistics<br />
should teach students the structure for what<br />
it communicates.<br />
Is the effort to teach the modern course<br />
worth it? We believe it is. Rather than a collection<br />
of techniques or a ‘cookbook’ of situations<br />
and formulas, a modern course in statistics<br />
must teach students to reason about the<br />
world. Although that makes the course more<br />
difficult to teach and assess, it will make a difference<br />
in students’ lives and serve them for the<br />
rest of their academic careers and beyond. ■<br />
