In order that no group should be too much affected by local conditions of examining, it 

 was made a rule that not over 250 cards should be taken in any one group from any one camp. 

 The only exception to this rule is in the case of development battalions and the officers' training 

 camps, where single batches of 500 cards were taken together. Under this rule it was not 

 possible always to obtain a sample so large as a thousand. All the groups for the trains fall 

 more or less short of a thousand (606 to 904). Only 421 nurses were found among the files, 

 and the trench mortar batteries furnished only 426 cases. 



It should be noted that the figures of table 7, like those of table 6, are the counts made 

 by hand. In a number of instances the sortings from the Hollerith program disagree. These 

 discrepancies are ordinarily due to errors of counting. In the case of the engineers they are 

 due to a subsequent elimination of men in the engineers train which were included in the 

 original counts. A large discrepancy in the case of the supply trains is similarly due to an 

 elimination during the Hollerith sorting of certain Quartermaster Corps men who did not prop- 

 erly belong to the supply train. The figures of table 7 are intended merely to show the extent 

 to which each group is dependent upon the particular conditions obtaining in separate camps. 



Group VIII, in addition to the comparison of military organizations, provides the only 

 data available in the principal sample for the comparative ratings of noncommissioned officers 

 and privates, since no noncommissioned officers were included among the recruits of Groups I 

 to III. It also gives an opportunity for a comparison of estabhshed organizations with the 

 draft. Presumably the building up of an organization exercises certain selective factors which 

 should be reflected in the intelligence ratings of the organization when established. 



A group of negro estabhshed organizations (Group IX), originally contemplated, was 

 abandoned because of the lack of record cards. 



Group X: Special experimental group. — For the sake of special statistical work a group of 

 1,047 white, English-speaking recruits was brought together from nine camps. This group 

 was obtained by a request sent to the camps in June, 1918, asking that unselected groups of 

 the white draft be given both examination alpha and examination beta, and, when possible, the 

 Stanford-'Binet examination. The request was sent to 12 camps, and response was received 

 from the 9 listed in table 8. The records returned from the camps were gone over, and all 

 cards of men not born in English-speaking countries were eliminated. It was thought that
