Two-Way Variance Analysis Post 2
As an update to Two-Way Variance Analysis Post 1, the example below shows the generally accepted calculation as well as notes (A and B) describing the components of the calculation.
The right side of the example shows a simple alternative method to perform the calculation. In my opinion this method is easier to remember and understand because it keys in on the percent change only of each component of variance. In other words, you don't need to remember footnotes A and B to perform the calculation. This can be especially useful when performing analysis of more than two components as the calculations get much more complex.
