A set of X and Y scores has a Pearson correlation of r = -0.60.For these data,60% of the variability in the Y scores can be predicted from the relationship with X.

Question

The coefficient of determination, which is the square of the Pearson correlation coefficient (r^2), indicates the proportion of the variance in the dependent variable that is predictable from the independent variable. In this case, r^2 = (-0.60)^2 = 0.36, meaning 36% of the variability in Y scores can be predicted from X, not 60%.
