The sums of squares components relates such that SS between is equal to
A) SS within
B) SS total - SS within
C) SS total + SS within
D) none of these

Question

Quizplus · Accepted Answer

The total sum of squares (SST) is equal to the variance multiplied by the total degrees of freedom. SS within is the sum of squares of the differences between each observation and its group mean. Consequently, SS between is SST minus SS within. Therefore, the correct relation is SS between = SST - SS within.
