[Vol. XV, 



Group number was not coded on the psychological record card ' but was marked on each 

 package of cards. It was punched, however, on each Hollerith card. 



Personal information was coded in red ink along the left-hand margin of the upper part 

 of the card in the following order: Camp, State, age, rank, arm, nativity, years in United 

 States, schooling. An omitted item was indicated by "X" or "XX." 



The column of raw scores in the separate tests to be punched on the Hollerith card was 

 checked. Raw scores were always used, even when weighted scores were given, in order to 

 place all data upon the same basis. When test 1 of beta was given with weighted score it was 

 an indication that the raw score had been assigned on the basis of a perfect score of 10 points. 

 Half the recorded value was in such cases written in so that test 1 might be scored in a manner 

 of the later rule. Test 8 in beta was never recorded, in order that the data might be com- 

 parable with the latest procedure for giving beta. When a score for it did occur it was marked 

 with an "X." 



The code numbers for type of individual examination, total score in individual examination, 

 and combination of examination were entered successively at the lower right-hand corner of 

 the card under "Mechanical Test." 



When any item was missing, illegible, doubtful, or obviously incorrect, and could not 

 therefore be coded, an "X" (or, for a two-digit number, "XX") was placed on the card in the 

 position in which the code number should have stood.
