In statistics spearman s rank correlation coefficient or spearman s ρ named after charles spearman and often denoted by the greek letter ρ displaystyle rho or as r s displaystyle r s is a nonparametric measure of rank correlation.
The spearman correlation between two variables is equal to the pearson correlation between the rank values of those two variables.
Spearman s correlation assesses the degree of linear association between two variables measured at the ordinal level. Critical values of the spearman s ranked correlation coefficient r s taken from zar 1984 table b 19. The spearman s rank coefficient of correlation is a nonparametric measure of rank correlation statistical dependence of ranking between two variables.
