In table 199 will be found the percentages of final letter grades made on all examinations 

 by enlisted men of the 15 camps used in this study. Figure 18 presents the same data shown 

 in table 199, with the camps arranged in the rank order of the percentage of men scoring better 

 than D. The percentage of men scoring D, D — , or E ranges from only 8.4 per cent in Camp 

 Lewis to 42.7 per cent in Camp Lee. There is a range in the percentage of A grades from 1.6 

 per cent in Camp Lee to 6.1 per cent in Camps Lewis and Devens. Considering A and B grades 

 combined there is a range from 5.8 per cent in Camp Lee to 18.7 per cent in Camp Lewis. There 

 is not always a perfect agreement between the percentage of low grades and the percentage of 

 high grades. Camp Devens, for instance, is fifth on the basis of grades better than D, but 

 would stand second if the camps were arranged in the rank order of A and B grades combined. 



The fact that camp differences of such large magnitude have been found, together with 

 the fact that men were sent to the camps largely on a geographical basis, suggests that there 

 probably are more or less marked differences in the levels of intelligence in different parts of 

 the country. Because it has been shown, however, in the early part of this chapter that the 

 reliability of these data can not be unequivocally demonstrated, it is not safe or wise to make 

 such geographic comparison on the data which are at present available.
