Between group variability in samples is related to the difference between the grand mean and the successive sample means.

Question

Quizplus · Accepted Answer

The between group variability (also known as the between group sum of squares) is calculated by taking the sum of the squared differences between the grand mean and each individual sample mean, multiplied by the sample size. Therefore, it is directly related to the difference between the grand mean and successive sample means.
