WebSep 1, 2024 · Bivariate correlation coefficients: Pearson's r, Spearman's rho (r s) and Kendall's Tau (τ) Those tests use the data from the two variables and test if there is a linear relationship between them or not. Therefore, the first step is to check the relationship by a scatterplot for linearity. WebPearson/Spearman correlation coefficients between X and Y are shown when the two variables' ranges are unrestricted, and when the range of X is restricted to the interval (0,1). Most correlation measures are sensitive to the manner in which X and Y are sampled. Dependencies tend to be stronger if viewed over a wider range of values.
