WebA strong correlation might indicate causality, but there could easily be other explanations: It may be the result of random chance, where the variables appear to be related, but there is no true underlying relationship. There may be a third, lurking variable that that makes the relationship appear stronger (or weaker) than it actually is. WebTo 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.
