Strength of Correlation

Question 84515 • Common Core Algebra I - MA3109 B-CR (4Q 0.25 credit) (due 10/29 or will be grade of F)

Which correlation coefficient represents a moderate negative correlation?

Answer
A
r = –0.04
B
r = –0.24
C
r = –0.64
D
r = –0.94

Explanation

A negative correlation has an r-value below 0, and its strength depends on how far r is from 0. A moderate negative correlation is typically around −0.5 to −0.7, so r = −0.64 fits. The value −0.94 is very strong, while −0.04 and −0.24 are weak.
