 ==== Correlation ====
-The correlation is use in statistics and probability. It is the intensity of the link between one and several variables. The study of this link can be done by looking for example at the linear correlation coefficient ; if the value of this coefficient is near -1 there is a negative correlation, and if the value is near 1 there is a positive correlation.
+The correlation is used in statistics and probability. It measures the intensity of the link between one and one or several other variables.

 \\ A correlation can pinpoint a link between two variables even if they don't have any causality link.
