How to calculate spearman's rank correlation
WebDue to the non-normal distribution, I used Spearman's rank-order correlation, which returns a correlation coefficient and a significance (p) value. My results (n=400) show a significant ( p = 8 × 10 − 5) but weak correlation (Spearman's ρ = .20). WebAnswer. To determine Spearman’s correlation coefficient, we will use the formula 𝑟 = 1 − 6 ∑ 𝑑 𝑛 ( 𝑛 − 1) , where 𝑟 represents the coefficient, 𝑛 is the number of data pairs, and 𝑑 is the square of the difference in the ranks of the two coordinates for each data pair.
