Everything about Correlation
Statistical relationship
In statistics, correlation is a type of statistical relationship between two random variables or bivariate data. It usually refers to the extent to which a pair of quantities are linearly related. More generally, an arbitrary relationship between variables is called an association, meaning the degree to which the variability in one can be accounted for by the other. Wikipedia →

📖 Definitions
Noun A reciprocal, parallel or complementary relationship between two or more comparable objects.
Noun One of the several measures of the linear statistical relationship between two random variables, indicating both the strength and direction of the relationship.
Noun An isomorphism from a projective space to the dual of a projective space, often to the dual of itself.
