Pearson r moment correlation formula
Did you know?
WebPearson called his equation the product moment correlation coefficient. We typically now refer to it as the Pearson's r. The calculation is based on the concept of the Z scores; specifically, taking the mean of the Z score products from the X and Y variables. The formula for Pearson's r is: WebThis article focuses on the Pearson product-moment cor- relation coefficient. Pearson's r was the first formal cor- relation measure, and it is still the most widely used measure of relationship. Indeed, many "competing" correlation in- dexes are in fact special cases of Pearson's formula. Spear- man's rho, the point-biserial correlation, and ...
