A modification of Kendall's test for independence is described which allows one to test for association in a bivariate distribution as measured by Kendall's tau, a property not shared by Kendall's procedure. The proposed procedure, however, still provides an exactly distribution- free test of independence. The test procedure is inverted to obtain a confidence interval for tau which has distinct advantages over the currently employed confidence interval.
