Abstract
The connexion has been shown between two methods of calculating critical values used in the problem of comparing two mean values. The methods are: (i) a predominantly numerical method and (ii) a method involving first the expression of the critical values in a series of groups of algebraic-terms of different orders. This latter method has been already used in the computation of tables. The close connexion between the two methods helps to emphasize what the series method is doing. A particular case (viz. f1 = f2 = 20) is discussed at some length, the important comparisons being between the figures given in Tables 9 and 10.Keywords
