Is covariance a measure of variability?

Strictly speaking, covariance is not a measure of variability (interquartile range, standard deviation, etc. It is used to describe variability). Instead, it is a measure of association because it tells you the relationship between two variables.

What is measure by covariance?

covariance. In probability and statistics, covariance is a measure of the total variability of two random variables. If higher values ​​of one variable generally correspond to higher values ​​of another variable, and the same is true for lower values ​​(variables tend to behave the same), the covariance is positive.
