Question

Which correlation coefficient indicated the strongest linear relationship between the variables?

A: 0.65
B: -0.87
C: -0.52
D: 0.8

Answer 1

B

Explanation:

since the strongest correlation is either 1 or negative 1, and weakest is closer to 0,

now, lets order from weakest to strongest:

-0.52,0.65, 0.8, -0.87

Since -0.87 is closest to negative one than others to -1 or 1, it has the strongest linear relationship
