F Value Calculation Information (ANOVA)

If the output option “Display F Value Calculation Information” is selected, the program will add information on how the F value was calculated to the ANOVA worksheet.

If your design is a crossed design containing fixed factors only, the F value is easily determined. In this case F is simply the mean square for the component divided by the mean square error. However, this is not true when random factors are involved or there are nested designs. In this case, you have to use the expected mean squares to determine what to divide the mean square for the component by to obtain a F value.
