Question

question 4 of 10
which of these r-values represents the weakest correlation?
a. 0.5
b. 0.3
c. 0.4
d. 0.2

Explanation:

Correlation coefficients (r-values) range from -1 to 1. The strength of correlation is determined by how close the absolute value of r is to 0; values closer to 0 indicate a weaker linear relationship. Comparing the given positive values, 0.2 is the closest to 0.

Answer:

D. 0.2
