In performing a two-way ANOVA for a two-factor factorial experiment,the error sum of squares,SSE,equals:
A)SST - SS(groups)- SS(int)
B)SST - SS(1)- SS(2)- SSE
C)SST - SS(int)- SS(1)- SS(2)
D)SST - SS(1)- SS(2)
E)SST - SS(int)

In a two-way ANOVA, the total sum of squares (SST) is partitioned into the sum of squares due to the first factor (SS(1)), the sum of squares due to the second factor (SS(2)), the sum of squares due to the interaction between the two factors (SS(int)), and the error sum of squares (SSE). Therefore, SSE is calculated as SST minus SS(1), SS(2), and SS(int), which matches option C.
