Which indicator shows how well a regression line fits through the scatter of data points? A)F-test B)R² C)t-test D)Durbin-Watson test

Question

Quizplus · Accepted Answer

The R² indicator, also known as the coefficient of determination or R-squared value, measures the proportion of variability in the dependent variable that can be explained by the independent variable(s) in a regression model. A higher R-squared value indicates a better fit between the regression line and the data points. Therefore, it is the best indicator for measuring how well a regression line fits through the scatter of data points. The other options (F-test, t-test, Durbin-Watson test) are statistical tests for other purposes and are not directly related to measuring the fit of a regression line.
