Question

Which of these r-values represents the strongest correlation ?

A. -.07
B. -0.8
C. -0.6
D. -0.5

Answer 1

B. -0.8

Explanation:

A correlation coefficient ranges from -1 to 1, with -1 being a perfect fit for a decreasing set of data and 1 being a perfect fit for an increasing set of data.

The closest to either 1 or -1 in this problem is -0.8, so this is the best fit.

Answer 2

B because -0.8 is the closest to -1
