Comparing the Pearson and Spearman correlation coefficients across distributions and sample sizes: A tutorial using simulations and empirical data
You share, we take care!' -Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in The Pearson product-moment correlation coefficient (r p ) and the Spearman rank correlation coefficient (r s ) are widely used in psychological research. We compare r p and r s on 3 criteria: variability, bias with respect to the population value, and robustness to an outlier. Using simulations across low (N ϭ 5) to high (N ϭ 1,000) sample sizes we show that, for normallydoi:10.1037/met0000079 pmid:27213982 fatcat:zzaan2i47fejnnahmqbm63m6o4
