WebSpearman correlation coefficient (rho) The Spearman coefficient is based on the ranks of the observations and not on their value. It can be thus be considered as non parametric. This coefficient is adapted to ordinal data. One can interpret this coefficient in terms of explained variability of the ranks. Kendall correlation coefficient (tau)

There are two methods to calculate Spearman's correlation depending on whether: (1) your data does not have tied ranks or (2) your data has tied ranks.
