[Vol. XV, 



The data for the women from various colleges (table 430) again emphasize the differences 

 between institutions. The variations are not so great as they were in the case of the college 

 men, but they are large enough to be of significance. 



None of the normal schools reported records of enough men to make a study of the 

 differences worth while, but the fact that there are large differences between normal schools 

 as well as between colleges is shown in table 431, which gives the results of four groups of 

 normal-school women. 



In table 432 the division is by sex. While the median scores made by the women are 

 in every case a few points lower than the median scores for the men in similar groups, the 

 differences are so small that they may be regarded as insignificant. The same statement 

 may be made regarding the percentage of A and B grades combined. The men tend toward 

 a higher proportion of A grades. 



As the figures sent in by the University of Illinois were grouped according to the depart- 

 ment of study, it was possible to investigate intelligence differences between the various de- 

 partments. These data are set forth in table 433. As would be expected, the graduate 

 students rate considerably higher than the students in the undergraduate departments, but 

 this is the only difference of importance. The very slight drop for the students of agriculture 

 is probably not significant. 



Differences between the men in the four years of college were also obtained from the 

 Illinois data, and the results of this study are shown in table 434. There is a slight but 

 definite increase in the percentage of higher grades with the longer stay at college, presumably 

 as the result of the elimination of poorer men by the ordinary collegiate process.
