Use this method to calculate Spearman rank correlation, create an example

Another option is simply to use the full version of Spearman's formula (actually a slightly modified Pearson's r), which will deal with tied ranks: n R(x;) - R(x)) .(R(y.) - R(y) Sxy i=1 P= S.Sy n ( R( X.) - R(X) ) " ) . (. ( R( ) - R(X ) N i= Full Spearman's r formula (Clef, 2013. p. 4) Where: . R(x) and R(y) are the ranks, . R(x)bar and R(y)bar are the mean ranks
