Table 189. — Variables: Beta scoreXeamp. Groups I, II, III: White draft. 



For all men who took beta, as beta only, alpha and beta only, beta with an individual examination, or alpha, beta, and 



an individual examination. 



Because there were great differences in procedure employed in the psychological work at 

 the various camps there is some question as to the reliability of the comparisons that can be 

 made on the basis of the figures available. A phase of these differences is shown in table 190, 

 which presents the percentages of final grades made on each type of examination in the various 

 camps. At Camp Taylor 87.5 per cent of the men examined took alpha only, while in Camp 

 Meade the percentage of men taking alpha only was 54.8. There is also a wide range of dif- 

 ference in the men who were graded on the basis of the beta examination; i. e., the men who 

 took beta only or a combination of alpha and beta only. In Camp Taylor 11.2 per cent of the 

 men received their final grades on the basis of beta scores, while in Camp Upton 31.8 per cent 

 of the men were graded by beta. In the case of the individual examinations we find further 

 differences; 6.8 per cent of the men were given individual examinations at Camp Travis, while 

 only 0.7 per cent were given individual examinations at Camp Lee. At Camp Upton 70 per 

 cent of the men who took individual examination were given the performance scale, 30 per 

 cent the Stanford-Binet examination. At Camp Funston, on the other hand, only 15 per cent 

 were tested on the performance scale, while 70 per cent were given the Stanford-Binet, and the 

 remaining 15 per cent the point scale. On this basis it is clear that unless all types of examina- 

 tions were standardized so that the letter grades given on them mean approximately the same
