Abstract

Goodman and Kruska's τ measure of categorical association is advanced as a replacement for conventional measures of effect size for r × c contingency tables. Goodman and Kruskal's τ is an asymmetric measure of categorical association which is based entirely on the observed data and possesses a clear interpretation in terms of proportional reduction in error. Comparisons with conventional measures of effect size based on chi-squared such as Pearson's φ2, Tschuprow's T2, and Cramér's V2 demonstrate the advantages of employing τ as a measure of effect size.
