To calculate a Spearman rank-order correlation on data without any ties we will use the following data: Where d = difference between ranks and d 2 = difference squared. … WebSpearman's may have less power than Pearson's when the (estimated) linear relationship is nicely linear, without a lot of curves. However, Spearman's has more power when the linear relationship has a lot of curves (and is still monotonic). This article has a bit more info on the topic. They're talking about 'tails', which means the lower or ...
