Pearson’s correlation coefficient Definition, Formula, & Facts

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. WebThe Pearson correlation coefficient [1] measures the linear relationship between two datasets. Like other correlation coefficients, this one varies between -1 and +1 with 0 … WebStep one: Create a Pearson correlation coefficient table. Make a data chart, including both the variables.
