If r² = 0.77, then 33% of the variation in Y is explained by variables other than the one in the regression.

Question

Quizplus · Accepted Answer

The coefficient r² = 0.77 represents the square of the correlation coefficient (R^2) in a regression analysis, which indicates that 77% of the variation in Y is explained by the variable in the regression, leaving 23% of the variation in Y explained by variables other than the one in the regression, not 33%.
