Quizplus · Accepted Answer

Covariance measures the direction and strength of the relationship between two variables. Positive covariance means that as one variable increases, the other variable also tends to increase. Therefore, there is a positive relation between the x and y variables. Choices A, B, and C are incorrect as they do not properly describe the meaning of covariance.
