Spearman's correlation coefficient, (ρ, also signified by rs) measures … WebAug 4, 2024 · Pearson correlation assumes that the data we are comparing is normally distributed. When that assumption is not true, the correlation value is reflecting the true association. Spearman correlation does not assume that data is from a specific distribution, so it is a non-parametric correlation measure.
WebThe Spearman rank-order correlation coefficient is a nonparametric measure of the monotonicity of the relationship between two datasets. Like other correlation coefficients, this one varies between -1 and +1 with 0 implying no correlation. Correlations of -1 or +1 imply an exact monotonic relationship. http://connectioncenter.3m.com/pearson+of+spearman+correlation+example+in+research
