Difference between spearman rank and pearson
WebAs compared to Pearson coefficient, the interpretation of Kendall's tau seems to me less direct than that of Spearman's rho, in the sense that it quantifies the difference between the % of concordant and discordant pairs among all possible pairwise events. In my understanding, Kendall's tau more closely resembles Goodman-Kruskal Gamma.

WebApr 11, 2024 · Consequently, the Spearman rank correlation coefficient ρ as defined by Eq. (3) was adopted to evaluate the correlation regardless of the data distribution (Kavussi and Motevalizadeh, 2024), (3) ρ = 1 − 6 ∑ i = 1 n d i 2 n n 2 − 1 where d i is the difference between a pair of ranks and n is the number of observations. Webthese ranks were related to another set of ranks, say for a second type of product. The association between the two sets of rank scores is described by the Spearman's rho. Notice the correlation coefficient and the p-value are exactly the same for the two analyses (Pearson’s correlation on the left and Spearman’s rho on the right).
