Question

The pet shop decides to run their analysis as a regression, and finds an error mean sum of squares of 6.8, and an F-statistic of 6.2. What is the between-group variance?

Answer 1

42.16

Explanation:

Calculation for the between-group variance

Using this formula

The between-group variance=Error mean sum of squares *F - statistic

Let plug in the formula

The between-group variance = 6.8 * 6.2

The between-group variance= 42.16

Therefore the The between-group variance will be 42.16
