A)0.80%
B)80%
C)0.64%
D)64%

Question

Quizplus · Accepted Answer

The coefficient of correlation squared, r², gives the proportion of variance in the dependent variable that can be explained by the independent variable. In this case, r² = 0.8² = 0.64, meaning that 64% of the variation in the dependent variable is explained by the variation in the independent variable. Therefore, the correct answer is D) 64%.
