WebApr 10, 2024 · Le coefficient de corrélation de Pearson permet d'étudier la relation (ou corrélation) entre deux variables aléatoires quantitatives (échelle d'intervalle minimum); par exemple, la relation entre le poids et la taille. C'est une mesure qui nous donne des informations sur l'intensité et la direction de la relation. WebThe Pearson correlation coefficient test compares the mean value of the product of the standard scores of matched pairs of observations. Once performed, it yields a number that can range from -1 to +1. Positive figures are indicative of a positive correlation between the two variables, while negative values indicate a negative relationship.
