Distribution of Undergraduate Course Load for Faculty. by Gender and Discipline

Two statistical tests were carried out. First, a chi-square test of independence of rows was applied to determine whether the pattern of the number of under­graduate courses taught[124] by men and women differed. (These tests were either on three or four degrees of freedom.) The tests were not significant at the.05 level except for electrical engineering. It is important to mention that one could have different patterns without having women teach more of fewer courses. For instance, men might teach 1 or 2 courses more often than women do, who in turn might teach 0 or 3 courses more often, but where the mean number of courses remained close.

Therefore, we added a simple two-sample t-test of the average number of courses for men and women. The means are displayed below for each of the dis­ciplinary areas. The t-tests were all not significant at the.05 for the null hypothesis of no difference, again except for electrical engineering. It is clear from the table that men teach more undergraduate courses than do women.

NOTES: Rank is denoted as full (1), associate (2), or assistant (3) professor. Salaries are expressed as number of thousands of dollars with number of respondents in parentheses. For example, 34 men at the full professor rank in biology responded that they earn an average of $101,900 per year. Of 1,404 full-time faculty members who responded, only 1,179 included salary data. The salaries expressed are 9-month salaries. Some clearly high outliers were removed. Twenty percent of the respondents replied back with salaries below $100 for 9 months. Since it was likely that these values were actually in the thousands, these numbers were multiplied by 1,000 for the final value rather than omitting the information.
