quantity. If ρ(X, Y ) is close to zero, there is no clear linear trend between X and Y . Hence there is no clear trend between X and Y. If ρ(X, Y ) = 1 or ρ(X, Y ) = −1, Y is a linear function of X. This also shows that if value of ρ is close to 1 X and Y are strongly correlated. Here Y=aX + b such
