The summary table computed in the section on partitioning the sums of squares in ANOVA is reproduced below.

Source    df    Ssq     Ms     F     p
 Groups   2    8.000  4.000  3.60 0.071
 Error    9   10.000  1.111
Total    11   18.000  1.636

The values of η² and ω² can be computed as follows:




As you can see, η² is larger than ω².
