15. Alpha form number (no coding) : 



5. Form 5. 



6. Form 6. 



7. Form 7. 



8. Form 8. 



1&-31. Raw scores for separate tests: 

 Actual scores (no coding). 

 Check the column to be punched. 

 When both alpha and beta are on the same card, 

 check alpha. 



9. Form 9. 



When beta is checked, place an "X" in the raw- 

 score space for test 8. 



When beta is weighted and checked, write in 

 for test 1 one-half the raw score indicated. 



32, 33. Total raw alpha score (8 tests): 



Divide the score by 5 and drop the remainder. Precede a one-digit number by a "0." 



34, 35. Total raw beta score (7 tests): 



Divide the score by 5 and drop the remainder. Precede a one-digit number by a "0." 



36. Type of individual examination: 

 1. Performance scale. 



2. Point scale. 



37, 38. Total score in individual examination: 



Performance — Divide the number of points by 



5 and drop the remainder. 

 Point scale — Divide the number of points by 5 

 and drop the remainder. 



39. Combination of examination: 



1. Alpha only. 



2. Beta only. 



3. Individual only. 



4. Alpha and beta. 



5. Alpha and individual. 



3. Stanford-Binet scale. 



Stanford-Binet scale — Double the mental age 

 (expressed with one decimal) and drop the 

 decimal. Always precede a one-digit num- 

 ber by a "0." 



6. Beta and individual. 



7. Alpha, beta, and individual. 



The Hollerith card for mechanical sorting is reproduced, slightly diminished in size, 

 herewith in a figure. The information coded on the psychological record cards was transferred 

 to code slips on which the numbers were recorded regularly, one below another; the numbers 

 on the code slips were checked and then punched on the Hollerith card. (The procedure is 

 that of punching a hole through the proper number in each column. When an item is coded 

 by a two-digit number, then the ten's place is punched in the first column and the unit's in 

 the second.) The punching was also checked. 



Statistical record card used in mechanical sorting by Hollerith system. An information is coded in numerical values and holes punched in the 

 corresponding numbers on the- card. A two-digit number is represented by two holes in adjacent columns. The figure is reduced from 7| 

 inches long. 



The entire work of coding and sorting was delayed by the lack of adequate clerical and 

 statistical facilities. For coding, six clerks were available for a period of two months. In 

 this time they coded approximately 160,000 cards, which make up the principal sample. No
