"WebThe correlation coefficient r is directly related to the coefficient of determination r 2 in the obvious way. If r 2 is represented in decimal form, e.g. 0.39 or 0.87, then all we have to do to obtain r is to take the square root of r 2: \[r= \pm \sqrt{r^2}\] The sign of r depends on the sign of the estimated slope coefficient b 1:. If b 1 is negative, then r takes a negative sign. " - For a sample r 2 is equal to
