If the correlation coefficient is greater than 0.5 then the coefficient of determination R² from a simple regression model is greater than 0.25.

Question

Quizplus · Accepted Answer

This is true because the coefficient of determination (also known as R-squared) is equal to the square of the correlation coefficient, meaning that if the correlation is greater than 0.5, the coefficient of determination will be greater than 0.25 (0.5 squared is 0.25).
