WebApr 4, 2016 · In this example the Pearson correlation p ⌢ =0.531, while Spearman's ρ ⌢ =1. Thus, only the Spearman rho captures the perfect non-linear relationship between u i and v i. Note that the Pearson correlation p ⌢ =0.531 has a higher upward bias than the product-moment correlation p=0.161; this occurs due to the small sample size, n=12. WebSpearman’s rank correlation: A non-parametric measure of correlation, the Spearman correlation between two variables is equal to the Pearson correlation between the rank scores of those two variables; while Pearson’s correlation assesses linear relationships, Spearman’s correlation assesses monotonic relationships (whether linear or not).
