LEXMALE and LEXFEM are the life expectancies, at birth, for children born during 1995–2000. INFMORT
is the number of children who die, per 1,000 born, during the first year of life. SOURCE: Population Division
and Statistics Division of the UN Secretariat. World Population Prospects: The 1998 Revision, Vol. I: Comprehensive
Tables; Demographic Yearbook 1997; and Population and Vital Statistics Report, Statistical papers,
Series A Vol. LIII, No. 3. http://www.un.org/popin/wdtrends.htm
MFRATIO is the number of males per 100 females in 2000. SOURCE: calculated by the Statistics Division of
the UN Secretariat from Sex and Age Annual 1950–2050 (The 1998 Revision) (data on diskettes), supplemented
by Demographic Yearbook 1997.
TFR, or total fertility rate, is an estimate of the number of children a girl born during 1995–2000 will bear if
current fertility patterns hold and she lives through her entire child-bearing years. TFR is estimated by the
Population Division of the UN Secretariat. http://www.who.int/whr/en. TFR90 is the total fertility rate for
1990. SOURCE: World Health Report 2000
FEMILLIT is the percentages of women, 15 years of age who are illiterate. SOURCE: UNESCO Institute for
Statistics, assessment of February 2000, supplemented by UNESCO Statistical Yearbook 1999. http://www.uis

PCGDP is the per capita gross domestic product in 2000, calculated in U.S. dollars by the Statistics Division of
the UN Secretariat. http://www.un.org/esa
outliers, and even in large samples, it’s heavily influenced by big gaps in the
distribution of cases. The median, however, is not as strongly affected by
extreme scores. You can see this in table 19.9.

Using the data in table 19.8 as a proxy for the 200-or-so countries of the
world, the mean life expectancy for women in the world is 67.05 years and for
men it’s 62.55 years. If we remove the three cases in table 19.8 that have infant
