The formula to calculate the t-score of a correlation coefficient (r) is: t = r * √n-2 / √1-r2. The p-value is calculated as the corresponding two-sided p-value for the t-distribution with n-2 degrees of freedom. 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. svalbard global seed vault article
