Tip:Picture data points *re*-turning toward a line or curve that explains the *gress* (progression or relationship) between variables.

From Latin regressio (“a going back, return”), from regredior (“I go back”), from re- (“back”) + gradior (“I go, step”).

The term 'regression' in statistics was initially coined by Sir Francis Galton in the late 19th century to describe a biological phenomenon where offspring of unusually tall parents tended to be shorter than their parents, and the offspring of unusually short parents were taller than them. The word soon evolved to apply more broadly.

Memory tip

Think of a *re*-turn to a *gress* (step) backwards.
