Answer
Answer:
A. C, D, B, A, E, F
Explanation:
Step1: Understand correlation coefficient
The correlation coefficient $r$ ranges from - 1 to 1. A value of -1 is a perfect negative linear - relationship, 1 is a perfect positive linear - relationship, and 0 is no linear relationship.
Step2: Analyze plot C
Plot C has points randomly scattered, so $r\approx0$.
Step3: Analyze plot D
Plot D has a weak positive linear relationship, so $0 < r_D<1$ and $r_D$ is small.
Step4: Analyze plot B
Plot B has a weak negative linear relationship, so $- 1<r_B < 0$ and $|r_B|$ is small.
Step5: Analyze plot A
Plot A has a strong negative linear relationship, so $r_A$ is close to - 1.
Step6: Analyze plot E
Plot E has a moderate positive linear relationship, so $0 < r_E<1$ and $r_E>r_D$.
Step7: Analyze plot F
Plot F has a strong positive linear relationship, so $r_F$ is close to 1.
Step8: Order the correlation coefficients
Based on the above - analysis, the order from least to greatest is C, D, B, A, E, F.
