events (Mitts, 2008). Before tabulating these gender<br />

choices, the description of each TSA competitive event<br />

listed in the official guides for both middle <strong>and</strong> high school<br />

was examined; then based upon the Weber-Custer study, a<br />

predictive judgment was made by the researcher as to the<br />

type of event category in which it belonged. Out of a total<br />

of 64 events, it was determined that 26 were designing<br />

<strong>and</strong>/or communication-type events, <strong>and</strong> 26 were utilizingtype<br />

events.<br />

Definite conclusions were drawn from the resulting<br />

data. Male <strong>and</strong> female participants in these TSA state<br />

conferences differed in their preferences for types of<br />

competitive event activities. Males clearly had a strong<br />

bias for utilizing-type activities such as Dragster Design<br />

(7 out of 9 events), while females had a preference for<br />

nonutilizing design <strong>and</strong>/or communication-type events (10<br />

out of 10). These results were consistent with the findings<br />

of the Weber-Custer research. A correct prediction of<br />

gender preferences for TSA competitive events was made<br />

before data analysis in 20 out of 21 cases (95%) for which<br />

statistically significant results were found. Some TSA<br />

events were omitted from the study because there were not<br />

enough entrants to analyze validly. In addition, the data<br />

clearly suggested that both males <strong>and</strong> females prefer team<br />

activities by 77%. Of high importance to researchers, but<br />

of little utility to teachers, the validity <strong>and</strong> reliability of the<br />

Weber-Custer criteria as a predictor of gender preferences<br />

was confirmed.<br />

New Findings Discovered in the Mitts Study<br />

The original Mitts study used raw numbers of students<br />

selecting certain TSA events <strong>and</strong> the “Chi-Square” statistic<br />

as the basis for determining the predictive capability<br />

of the Weber-Custer assumptions. Thus, if the Weber-<br />

Custer approach predicted that the event “Manufacturing<br />

Prototype” would be favored by males, <strong>and</strong> then 10 boys<br />

<strong>and</strong> 8 girls actually entered the contest, it would appear<br />

that boys preferred this event. However, if the same data is<br />

reexamined based on percentages of the total numbers of<br />

girls <strong>and</strong> boys attending the conference selecting this event,<br />

we see that the 10 boys were from a group of 244 total<br />

(4.10%) while of the total girls present (115) the 8 selecting<br />

this event represents 6.96%. In actuality, the percentage of<br />

girls selecting Manufacturing Prototype at this particular<br />

conference was slightly higher than the percentage of boys.<br />

Hence, the present study reexamines all of the Mitts (2008)<br />

data to provide information easily understood in laymen’s<br />

terms concerning which activities <strong>and</strong> TSA competitive<br />

events might be more attractive to girls, which are more<br />

or less neutral, <strong>and</strong> which boys prefer. It is acknowledged<br />

that this casual approach of examining percentages does<br />

not rise to the level of statistical significance available via<br />

the Chi-Square technique, but it allows us to make good<br />

guesses about cases with small numbers, whereas it could<br />

take several years of collecting data to attain statistical<br />

significance for them.<br />

In the reexamination of data from the Mitts study,<br />

columns were added to the original data tables showing<br />

the percentages of males <strong>and</strong> females selecting each<br />

competitive event, while the previous columns concerning<br />

the Weber-Custer predictions were deleted. The resulting<br />

tables, including the columns of percentages (Tables 3 <strong>and</strong><br />

4 for middle school <strong>and</strong> high school), were then examined<br />

<strong>and</strong> used to identify specific events favored by males or<br />

females <strong>and</strong> an informal indication of the magnitude of<br />

their preferences. The following scale of capital <strong>and</strong> lower<br />

case letters indicating magnitude was used to indicate<br />

preferences:<br />

M = Strong Male preference (more than 5% points)<br />

m = slight Male preference (1-4.99 % points)<br />

none = no preference (less than 1% point difference)<br />

N-F = <strong>No</strong> Finding, 0 females entered the event, so any<br />

apparent finding is invalid<br />

f = slight female preference (1-4.99 % points)<br />

F = Strong Female preference (more than 5% points)<br />
