Définition Dependence
If two or more variables affect each other, we will talk of a statistical dependence or relationship. The strength of a dependence between variables can be measured simultaneously – for example, we could investigate to what extent the looks of a person influence his personal income and vice versa. The grade of such a relationship is referred to as correlation and can be measured by methods such as the Spearman's rank correlation coefficient.
