For a 2xk contingency table when all the k groups fall into a natural order and for which a sequence of k values × may be assigned, ARMITAGE (1955) has suggested a X 2 (1) test statistic for the hypothesis H t of a trend in the proportions; This note considers a statistic for H t based on midrank values for the binary observations. It is shown that the proposed rank‐order test for H t coincides with that of ARMITAGE (1955).
