Question

If covariance of two variables X and Y is less than 0. What does it implies?

Answer 1

The correlation coefficient denoted as x is greater than zero it's a positive relationship. Conversely anytime the value is less than zero it's a negative relationship. The value of zero indicates that there is no relationship between the two variables.

Answer 2

If covariance of two variables X and Y is less than 0 then, it implies that the relationship between the variable is negative i.e. both of them go in different direction.  

1. Covariance measures relationship between two variables and identifies the degree up to which they both change together or how change in one variable leads to change in another variable.
2. It can be zero, positive as well as negative.
