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



examination. 



BETA SCORE. 



Of considerable importance is the question as to how many selective factors besides rank 

 enter into the figures here presented. It is not likely that peculiarities of particular camps 

 at which the men were examined brought about any great degree of selection; as, for instance, 

 in the case of the enlisted men the intelligence records were selected so as to include a propor- 

 tional number of men of each rank from each camp. It has already been shown in chapter — 

 that the camp has little to do with the standing of the officers except in the cases where all 

 the officers from a camp are in the same arm. Age probably does not cause much selection 

 among the enlisted men because correlational studies show that there is very little change 

 in the scores made by the men between the ages of 20 to 30. In the case of the officers, some 

 of the figures may be influenced by the fact that the Medical Department has a great many 

 older men, but as these are later separated for other reasons, the selection does not operate in 

 the final figures. 



The distribution of intelligence ratings by rank is shown in table 406. For the officers 

 the ratings are based on the score made in alpha, but, since the enlisted men did not all take 

 the same examination, the grades assigned to them are those made on alpha, beta, or individual 

 examinations, according to the following plan : 



Table 406. — Percentages of intelligence ratings by rank for white draft, u-hite enlisted -men and white officers. 



1 The group of sergeants includes sergeants, sergeants first class, and sergeants major. 



It is at once clear that there is a high positive correlation between the rank and the 

 intelligence rating of the enlisted men, and that the officers as a group rate much higher than 

 the enlisted men. The relationship among the officers of the various ranks is not so clear.
