In order to obtain a more direct comparison of the intelligence requirements of the occupations a composite graph 

 (Pig. 57) wa? prepared. This shows the median and range of the middle 50 per cent for each occupation. In this 

 graph the occupations are arranged in order from inferior to superior based upon the position of the median score in 

 the letter-grade intervals, irrespective of the number of cases from which the median was calculated. The position 

 of the median and quartile scores were computed from the percentage distributions of letter grades.
