For a two-way ANOVA with no interaction, the error sum of squares (SSE) is calculated as the total sum of squares (SST) minus the sum of squares for factor A (SSA) and the sum of squares for factor B (SSB). Therefore, the correct formula is SSE = SST - (SSA + SSB). Option D is the only choice that has this formula.
