Définition Causality
We will speak of causality, if there is an interdependence of cause and effect between two variables. Correlation can indicate causal relationships. A person who is a heavy smoker (variable X) has a higher risk of suffering from lung cancer (variable Y). Keep in mind though, that a correlation in itself does not prove causality. Two variables can have a statistical relationship without there actually being a mutual influence. In this context we also speak of spurious correlation.
