Notes. Kendall’s Tau, Spearman’s Rho and Pearson’s r scores and equivalent p-values in the parentheses. The results are significant for p < 0.05. If the result is not significant, the p-value is accompanied by an x mark. The number of data points used for each line are provided in the parentheses next to the line name.
