Question

Which correlation coefficient would indicate a strong negative correlation? a. r = -0.93 b. r = -0.23 c. r = 0.75 d. r = 1.0

Answer 1

A. r = -0.93

Explanation:

First, if there is a negative correlation, the correlation coefficient will be negative.

This eliminates answer choices C and D, which are positive.

If there is a strong correlation, the correlation coefficient will be closer to 1, or -1 (since the correlation is negative).

Since -0.93 is closer than -0.23 to 1, it has a stronger correlation.

So, the correct answer is A. r = -0.93
