The presence of the interaction term (SSAB) in the equation indicates that there are two factors being considered in the ANOVA model, and that their effects on the outcome measure are not additive. This corresponds to a two-factor ANOVA with interaction. The other choices (one-factor ANOVA, three-factor ANOVA, randomized block design) do not involve an interaction term in their equations.

The Following Equation SST = SSA + SSB +SSAB +SSE
