Definition of Correlation: Correlation is a statistical technique that is used to measure and describe the STRENGTH and DIRECTION of the relationship between two variables. Correlation requires two scores from the SAME individuals.
Correlation derives from the Latin cor- 'together' and -relatio 'relation'ââthe word is all about things that go together. But beware: just because a study shows a correlation between two variables, it doesn't mean one necessarily causes the other. There is a significant correlation between going to high school and being a teenager, but that doesn't mean that going to high school causes you to be a teenager.
