which of these r - values represents the weakest correlation?\na. 0.4\nb. 0.2\nc. 0.3\nd. 0.5
Answer
Explanation:
Step1: Understand correlation strength
The closer the absolute - value of the correlation coefficient ($r$) is to 0, the weaker the correlation.
Step2: Compare absolute - values
We need to find the smallest value among 0.4, 0.2, 0.3, and 0.5. Comparing the values: 0.2 < 0.3 < 0.4 < 0.5.
Answer:
B. 0.2
