Assessing Magnitude of Effect from Rank-Order Correlation Coefficients.
Strahan, Robert F.
Educational and Psychological Measurement, v42 n3 p763-65 Fall 1982
While Spearman's rho and Kendall's tau are equally powerful rank-order correlation coefficients under conditions of normality, they have different metrics. Applied to the same data, tau is smaller in absolute value, often no more than two-thirds of the size of rho. This difference in correlational metric appears to need emphasis. (Author/CM)
