Sex Differences 



In order to study the question of sex differences the results 

 for the visual vocabulary test were worked up in the following 

 manner: The returns for each city were divided into two groups, 

 boys and girls, and the average error for each sex was computed for 

 each line and for the test as a whole. The figures are given in 

 Table 13. City 1 reported 219 boys and 265 girls who made 

 respectively for lines 4 to 11 average errors as follows: .41 — .28, 

 .79— .61, 1.21— .97, 1.95—1.31, 2.64—2.38, 3.05—3.06, 2.95—2.39, 

 4.10—3.90, 2.17—2.16. For the test as a whole, the average 

 error was 17.87—15.61. It should be remembered that the high- 

 est average possible was 5 for each of lines 4 to 10, for line 11, 

 and 43 for the entire test. In the case of every line except 9, the 

 boys made a higher average error than did the girls. Consider-

 proportional to number of errors. Figures on ordinate indicate number of 

 errors. Total number of possible errors was 43. Open column equals girls; 

 closed column equals boys. Numbers below equal cities.
