There are differences in the interpretation of rS and t. Spearmans rS is the Pearson product-moment correlation coefficient between the two sets of rankings, corrected for ties. Kendalls t is the difference between the probability that, in the data, x and y are in the same order and the probability that , x and y are in the different orders. Consider two randomly selected data pairs (x1, y1) and (x2, y2). If x1 > x2, what is the probability of y1 > y2?
