In a simple linear regression problem, the least squares line is $\ddot {p}$ = -3.75 + 1.25 $x$ , and the coefficient of determination is 0.81. The coefficient of correlation must be 0.90.

Question

Quizplus · Accepted Answer

The coefficient of determination (R²) is the square of the coefficient of correlation (r). If R² = 0.81, then r = √0.81 = 0.90.
