Choosing a nonparametric test. How to test correlation between two variables which does not follow a linear pattern.

Mar 24 2021 By extension the Pearson Correlation evaluates whether there is statistical evidence for a linear relationship among the same pairs of variables in the population represented by a population correlation coefficient ρ rho. Kendall rank correlation is a non-parametric test that measures the strength of dependence between two variables. Decision-making process in the Linearity Test. In general a researcher should use the hypothesis test for the population correlation rho to learn of a linear association between two variables when it isnt obvious which variable should be regarded as the response.
