CHAPTER 20. 



DISTRIBUTION OF SCORES OK THE TESTS IN EXAMINATIONS ALPHA AND BETA. 



The following tables present the distributions of scores on the separate tests of the alpha 

 and beta examinations as they were found among officers and among white and negro recruits. 

 For the alpha tests these groups are unselected officers and unselected recruits; for the beta 

 tests the recruit groups, both white and negro, include only men who were too illiterate to 

 take the written examination or who had failed on it. These beta groups can not be fully 

 defined; in fact the way in which they were selected differed from camp to camp. As norms, 

 therefore, these distributions of scores oh beta tests are suggestive merely; but for making 

 comparisons of the beta tests with one another they may properly be used.
