Question

A: -0.55
B: -0.35
C: -0.25
D: -0.45

Answer 1

Answer: C

Explanation:

Answer 2

Apply the absolute value to each number. In other words, remove the negative sign to determine the positive version of that number.

-0.55 turns into 0.55
-0.35 turns into 0.35
-0.25 turns into 0.25
-0.45 turns into 0.45

The smallest result is 0.25, which is closest to 0. The closer r is to 0, the weaker the correlation.

Answer: Choice C) -0.25
