WebThe Pearson correlation coefficient is a number between -1 and 1. In general, the correlation expresses the degree that, on an average, two variables change correspondingly. If one variable increases when the second one increases, then there is a positive correlation. In this case the correlation coefficient will be closer to 1. WebComparing features: Like r, r 2 = 0 when the variables are completely unrelated. Unlike r 2, intermediate values of r do not have a PRE interpretation unless they are squared and thus transformed into r 2.
