When the individual values of A and B are not measured as 

 amounts of deviation from their central tendencies, but only as so 

 many A lJ s known to be less than Z and so many A 2 's greater than 

 Z, and as so many B^'s less than W and so many J3 2 's greater than 

 W, the per cents, of A 1 ^ 1 pairs, A*B 2 pairs, A 2 ^ 1 pairs and A 2 B 2 

 pairs give important information. 



The number and amount of the divergences of the ranks of the 

 second members from the ranks of their related first members also 

 give important information. 



If the two related facts are of the so-called normal distributionl 

 and the relationship is uniform for all amounts of A and each array! 

 is also a normal distribution, the Median Ratio, the Modal Ratio and!
