correlation
Significado: A mutual relationship or connection between two or more things, especially one in which changes in one variable are associated with changes in another.
In statistics, correlation measures the strength and direction of the relationship between variables. A key principle in research is that correlation does not imply causation — two things may be linked without one causing the other. The word is widely used in academic writing, journalism, and data analysis.
