Table 195. — Percentage distribution by groups for three selected camps of the beta scores of men who took beta only or alpha 



and beta only. 



As the officers were not tested in all of the camps and as the selection of cards for this 

 study was made with no reference to this point, there are not data on officers from all the camps 

 where the psychological work was carried on. It was found that there were sufficient cases 

 from seventeen camps and table 196 shows the distribution of intelligence ratings in these 

 camps. In table 197 the camps are arranged in order of their rank according to the percentage 

 of A and B grades which were made by the officers of each camp. This table also includes 

 the percentage of A grades made at each camp and some figures which were obtained in previous 

 studies of the same sort.
