Question

Practice analyzing correlations.
Which correlation coefficient represents a moderate negative correlation?

r = –0.04
r = –0.24
r = –0.64
r = –0.94

Answer 1

r = –0.64

Explanation: correlation strength is judged by |r|. Values near 0 (–0.04) are negligible, ~0.1–0.3 (–0.24) are weak, ~0.5–0.7 (–0.64) are moderate, and values near –1 (–0.94) are very strong.
