Correlation coefficient
Describes the dependence between two variables, giving a value between r = +1 and −1. It is widely used in the sciences as a measure of the strength of linear dependence between two variables. Correlations can be trivial (0.0 < 0.1), small (> 0.1 < 0.3), moderate (> 0.3 < 0.5), large (> 0.5 < 0.7), very large (>0.7 < 0.9), and perfect (> 0.9 – 1).
