Because of the nature of this formula, the correlation coefficient always results in a value between -1 to 1. In some cases, the value can be 0 indicating no correlation between the variables. For other extreme ones, a value of -1 or 1 indicates a perfect ...
Web1.6 - (Pearson) Correlation Coefficient, r. The correlation coefficient, r, is directly related to the coefficient of determination R 2 in an 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 = ± R 2. The sign of r depends on the sign of the estimated ...
