Covariance
Statistical measure of the joint variability of two variables.
Covariance is a statistical measure indicating the direction of the linear relationship between two variables. A positive covariance means they tend to move in the same direction, while negative means they move in opposite directions. It's related to correlation, but its magnitude is harder to interpret directly as it's not standardized.
