Question

Which of these r-value represents the weakest correlation?

A. 0.4
B. 0.3
C. 0.2
D. 0.5

Answer 1

Should be C.

0 means no correlation, so 0.2 is the closest to 0.

Answer 2

Option C is correct.

The value of r=0.2 represents the weakest correlation.

Explanation:

Strongest correlation states that a linear relationship is indicated by a correlation coefficient of -1 or 1.

Weakest correlation states that a linear relationship is indicated by a correlation coefficient equal to 0 or if the value is nearest to 0, then it also represents the weakest correlation.

From the options, the only r-value that is very close to 0 is 0.2.

Therefore, the r-value represents the weakest correlation is, 0.2
