Question

Which could be the approximate value of the correlation coefficient for the accompanying scatter plot?

A) -0.85
B) -0.16
C) 0.21
D) 0.91

Answer 1

The answer is D. It is a positive correlation so I can't be negative. It also is a strong correlation so it cannot be 0.21. So the answer is D.

Answer 2

Answer:

D

Step-by-step explanation:

The chart shows a strong positive correlation, hence this eliminates the negatives. Then 0.91 is a higher(strong) correlation coefficent.
