How to solve spearman rank correlation
WebNov 19, 2024 · How the test works. Spearman rank correlation calculates the \(P\) value the same way as linear regression and correlation, except that you do it on ranks, not measurements. To convert a measurement variable to ranks, make the largest value \(1\), second largest \(2\), etc. Use the average ranks for ties; for example, if two observations … WebThe Formula for Spearman Rank Correlation $$ r_R = 1 – \frac{6\Sigma_i {d_i}^2}{n(n^2 – 1)} $$ where n is the number of data points of the two variables and d i is the difference …
