An experiment has a single factor with five groups and two values in each group.
In determining the among-group variation, there are 4 degrees of freedom.
In determining the within-group variation, there are 5 degrees of freedom.
In determining the total variation, there are 9 degrees of freedom.
Also, note that SSA=128, SSW = 40, SST = 168, MSA = 32, MSW = 8, and FSTAT = 4.
