WebThe Spearman’s rank coefficient of correlation is a nonparametric measure of rank correlation (statistical dependence of ranking between two variables). Named after Charles Spearman, it is often denoted by the Greek letter ‘ρ’ (rho) and is primarily used for data analysis. It measures the strength and direction of the association between ...

The most familiar measure of dependence between two quantities is the Pearson product-moment correlation coefficient (PPMCC), or "Pearson's correlation coefficient", commonly called simply "the correlation coefficient". It is obtained by taking the ratio of the covariance of the two variables in question of our numerical dataset, normalized to the square root of their variances. Mathe…
