Which of the following correlation coefficients represents t

Which of the following correlation coefficients represents the strongest linear relationship?

A) 0.29

      
B) -0.915

      
C) 0.864

      
D) -567

Solution

Correlation coeffcient between -1 and 0 represents negative linear relationship. Coefficient -1 represents the strongest negative linear relationship and 0 is weakest. Correlation coeffcient between 0 and 1 represents positive linear relationship. Coefficient 1 represents the strongest positive linear relationship and 0 is weakest.

So option (B) -0.915 represents the strongest linear relationship.
