Covariance
Covariance: A joint measure of how two variables vary around their means, with sign related to relationship direction. It depends on units and is not directly comparable across different pairs. Correlation normalises it using standard deviations. This perspective connects the definition with practical behaviour in artificial intelligence systems.
