The statistic L, introduced to test for concordance within and between two groups of rankings of k objects is shown to be related to several measures of internal rank correlation. It has been previously shown that Kendalls W is proportional to the average of the rank correlations of all pairs of rankings in a single group and the Pages L is essentially the average of the rank correlations of an external ranking with each ranking in a group suggested by Lyerly. Similarly L is here shown to be directly related to the average of all rank correlations between a ranking from one group with a ranking from the other group. Modified author abstract
