Abstract

Within the context of a contingency table, this note describes the relationship between Freeman's measure of associationθ and the asymmetric association measures developed by Somers. Theθ coefficient is appropriate for a contingency table in which the levels of one factor are ordered and the levels of the other factor are unordered; the indices defined by Somers are usually used when the levels of both factors are ordered and one is assumed to be the independent factor.
