As stated previously, f and i indicate the relations be- 

 tween financial success and native intelligence ; f and e, or n etc., 

 substitutes education or information, or the other qualities for 

 intelligence. 



Each successive column may be used as a criterion and 

 delta differences between it and all other columns may be found.

 r(in), etc. will be used to indicate the correlations between (f) 

 financial success and (i) native intelligence, between (i) native

 similarly used with all other characteristics. 



Continuing to assume that the rankings as given on the 

 various Form B's are correct for each particular group, it is 

 necessary to multiply the number of groups ranked many fold 

 in order to overcome the influence of such variable factors as
