Web3 Aug 2024 · One of the most widely used correlation coefficients is the Pearson correlation coefficient (usually denoted by r). Graphically, this can be understood as “how close is the data to the line of best fit?” r ranges from −1 to +1. Grey line is the line that fits the data the best. Image by author. If the points are very far away, r is close to 0 WebThe Spearman rank-order correlation coefficient is a nonparametric measure of the monotonicity of the relationship between two datasets.
