Quizplus · Accepted Answer

The mean square between treatments (MSTR) is calculated by dividing the sum of squares between treatments by the degrees of freedom between treatments. In this case, the sum of squares between treatments is 180 and the degrees of freedom between treatments is 3. Therefore, the MSTR is 180 / 3 = 60.
