The equation: Total SS = SST + SSB + SSE, applies to the completely randomized design (one-way ANOVA model).

The correct equation for a completely randomized design (one-way ANOVA model) is: Total SS = SST + SSE, where SST is the total sum of squares, and SSE is the sum of squares due to error. SSB (sum of squares between groups) is not a separate component in this model because SST already represents the total variability including between and within group variability.

The Equation: Total SS = SST + SSB + SSE
