Question

Quizplus · Accepted Answer

The sum of squares total is the sum of the variance and the mean squared error. The variance is the average of the squared deviations from the mean, and the mean squared error is the average of the squared deviations from the predicted values. In this case, the variance is 139.73 and the mean squared error is 0, so the sum of squares total is 139.73.

ÓX2 = 704 (ÓX)2 = 8464 ÓTj2 =3178

ÓX² = 704 (ÓX)²= 8464 ÓT_j²=3178
