For a Two Way ANOVA with two factors A and B, the Sum of Square equation is:-
SSTO = SSA + SSB + SSAB + SSE
SSTO = Total Sum of Squares
SSA = Sum of Squares due to Factor A
SSB = Sum of Squares due to Factor B SSAB = Sum of Squares due to Interaction of Factor A and Factor B SSE = Amount of Variability left unexplained taken as error
Now my question is, why does One Way ANOVA not have a SSE Term?
Im reading this book, Intermediate Statistics for Dummies. I was reading about ANOVA. For one way ANOVA the book says that the Total Sum of Squares is the Sum of Squares within and Sum of Squares Between. There is no Sum of Square Error Term in one way ANOVA. That's why I am asking this question.
