WebJan 30, 2024 · saket. 121 3. 3. You can compute the correlation only for subjects for which you have scores on both variables. That doesn't rule out trying to estimate the missing scores, but how you might do that in your situation is unclear. – Nick Cox. Jan 30, 2024 at 14:31. Add a comment. WebMar 23, 2024 · Let's use the formula from before to compute the Spearman correlation: rs = 5∗ 38 − (15)(15) √(5∗ 55− 152)√(5∗ 55 −152) = 181 532 = −0.7 r s = 5 ∗ 38 − ( 15) ( 15) ( 5 ∗ 55 − 15 2) ( 5 ∗ 55 − 15 2) = 181 532 = − 0.7 Great! Though, calculating this manually is time-consuming, and the best use of computers is to, well, compute things for us.
