Asked by Jared
If the slope of the regression line is negative and the correlation coefficient is -.5, coefficient of determination is:
- It would be -0.25.
Correlation coefficient = r and coefficient of determination = r^2. Then, coefficient of determination would be (-0.50)^2 = 0.25, but because slope is negative, the coefficient of determination would be also negative.
Can you check my answer if it is right or not?
