Pearson vs Spearman correlations: practical applications

WebSpearman's correlation coefficient, (ρ, also signified by rs) measures the strength and direction of association between two ranked variables. What are the assumptions of the test? You need two variables that are either ordinal, interval or ratio (see our Types of Variable guide if you need clarification). WebThe Spearman rank correlation coefficient, r s, is a nonparametric measure of correlation based on data ranks. It is obtained by ranking the values of the two variables ( X and Y) and calculating the Pearson r p on the resulting ranks, not the data itself. Again, PROC CORR will do all of these actual calculations for you.
