no. 3.] PSYCHOLOGICAL EXAMINING IN THE UNITED STATES ARMY. 557 



Table 1. — Group I: Whi'c drnft, pro-rated, by States. 



Numbers of cases in Group I of the principal sample. Figures show for every State numbers taking each examination, 

 the actual total number selected for the State, and the desired total on a pro-rata basis of 1 per 1,000 white male 

 population in 1910. The last column gives the total for Groups I and IT (cf. Table 2) taken together. These 

 figures are the maxima available for any one State. 



Accordingly the ratio of one recruit per thousand white male population was determined 

 upon as the basis. It was not possible to provide for any scattering of cards within a particular 

 State, except in the case of the few largest States. New York State, for example, was divided 

 into New York City, Lackawanna County (the industrial region of Buffalo), and the remainder 

 of the State, and cards were pulled proportionately for these three sections. Table 1 is an 

 analysis of Group I. The total numbers for Group I are shown in the third column from the 

 right; the pro-rated numbers in the second column from the right. It will be noted that the 

 discrepancies between the two columns are in most cases not great. They are probably due to 

 errors in counting (vide supra) and in some cases to an accidental inclusion of alternate cards 

 that had been saved for emergencies. The large shortages in the cases of Arizona, Florida, 

 Pennsylvania, and Virginia are due to a failure to find cards in sufficient quantity in the files. 

 This failure does not mean that men from these States were not examined, but merely that 

 their home States were not recorded on the back of their cards, either because of some mistake 

 in camp procedure or because they were examined after the discontinuance of the rule for entering 

 the address. At Camp Lee the home State was never entered on the cards of the beta examina- 

 tion; hence it was necessary to select the Virginia group, since it could not be obtained from 

 another camp, from companies that were obviously made up entirely of Virginian men. Only 

 a small part of the files was arranged by companies ; hence the total sample is too small.
