Covariance is a measure that indicates the extent to which two variables change together. If the greater values of one variable mainly correspond with the greater values of the other variable, and the same holds for the lesser values, i.e., the variables tend to show similar behavior, the covariance is positive. In contrast, if the greater values of one variable mainly correspond to the lesser values of the other, the covariance is negative. Covariance is a measure of how much two random variables vary together. It’s similar in concept to variance, but where variance tells you how a single variable varies, covariance tells you how two variables vary together.
