The correlation coefficient, or Pearson product-moment correlation coefficient (PMCC) is a numerical value between -1 and 1 that expresses the strength of the linear relationship between two variables.When r is closer to 1 it indicates a strong positive relationship. A value of 0 indicates that there is no relationship.Here are four points to try it with that make the calculation not too bad: Put these in the formula and you should get r = 0.891, a quite high correlation. Conversely, pick any four points that make a horizontal rectangle, for example (2, 2), (8, 2), (2, 6), (8, 6). If you calculate r for these points, it will be 0.Le coefficient de corrélation r est une valeur sans unité comprise entre -1 et 1. La significativité statistique est indiquée par une valeur p.
