WebThe Spearman’s rho (rs) correlation is a popular and widely used ordinal measure rho correlates ranks between two ordered variables. When both variables are measured on a numerical scale (e.g., weight, height), the most commonly used measure of the association is t h e P e r s o n ‘ s product-moment correlation coefficient (r). In statistics, the coefficient of determination, denoted R or r and pronounced "R squared", is the proportion of the variation in the dependent variable that is predictable from the independent variable(s).
