Quizplus · Accepted Answer

The F-test for testing the difference between means is equal to the ratio of the Mean Square for Treatment (or between groups) over the Mean Square for Error (or within groups). Therefore, the correct choice is (A) Treatment over Error. The Mean Square Total is used for testing the overall significance of the model and is not relevant for testing the difference between means. The Error over Treatment ratio is not correct because it is the opposite of what is required by the F-test.
