A statistical relation indicating that two or more phenomena behave in an interrelated manner?

A statistical relation indicating that two or more phenomena behave in an interrelated manner is known as correlation. This relationship can be positive, negative, or nonexistent, reflecting how changes in one variable may correspond to changes in another. Correlation does not imply causation, meaning that while two phenomena may be related, one does not necessarily cause the other. Understanding these relationships is crucial in fields like economics, psychology, and the natural sciences.
