Quizplus · Accepted Answer

R-square is the commonly used measure of goodness of fit for a regression equation. It represents the percentage of variation in the dependent variable that is explained by the independent variable(s) in the model. A higher value of R-square indicates a better fit of the model to the data. Therefore, option C is the correct answer. The other variables listed may provide useful information about the regression model but do not indicate the goodness of fit.
