The former is based on ranks, hence they are not measuring the … WebIf you aren't comfortable with Pearson's $\rho$, then Spearman's rank makes this a bit better because it rescales both the x-axis and the y-axis in a non-linear way (rank encoding) and then fits the trend line in the embedded (transformed) space. In practice, this seems to work well and it does improve robustness towards outliers or skew as ...
