www.sheffield.ac.ukcorrelation coefficient it is assumed that at least one of the variables is Normally distributed. If the data do not have a Normal distribution, a non-parametric correlation coefficient, Spearman's rho (rs), can be calculated. This is calculated in the same way as the Pearson correlation coefficient, except that the data are ordered by size and ...
