Anova two factor with replication
Select Input Range which is your data table (only numbers). In my sheet it is $A$1:$F$5. In each example (group of students) I have 3 samples. As Alpha I left default 0.05.
Anova test appears in the Output Range I defined.
Anova two factor with replication test could be useful for statistics of some sets of data. Excel does it really well.
