WebThe formula for computing Pearson's ρ (population product-moment correlation coefficient, rho) is as follows [1]: where cov(X,Y) is the covariance of the variables X and Y and σ X (sigma X) is the population standard deviation of X, and σ Y of Y. Mathematically, it is defined as the quality of least squares fitting to the original data.
In statistics, the Pearson correlation coefficient ― also known as Pearson's r, the Pearson product-moment correlation coefficient (PPMCC), the bivariate correlation, or colloquially simply as the correlation coefficient ― is a measure of linear correlation between two sets of data. It is the ratio between the … See more It was developed by Karl Pearson from a related idea introduced by Francis Galton in the 1880s, and for which the mathematical formula was derived and published by Auguste Bravais in 1844.
