The covariance measures the direction and magnitude of the linear relationship between two variables but does not give an indication of the strength of the relationship. The coefficient of correlation, on the other hand, gives a measure of both the direction and strength of the linear relationship between two variables. The variance is not a measure of the relationship between two variables.
