WebJan 14, 2024 · The Pearson correlation coefficient is most often denoted by r (and so this coefficient is also referred to as Pearson's r ). Interpretation of the Pearson correlation The sign of the Pearson correlation gives the direction of the relationship: If r is positive, it means that as one variable increases, the other tends to increase as well; and WebThe correlation coefficient can be calculated by first determining the covariance of the given variables. This value is then divided by the product of standard deviations for these variables. The equation given below summarizes the above concept:. ρxy = Cov(x,y) σxσy ρ x y = Cov ( x, y) σ x σ y. where,
