The mean square for the error term in a two-factor between-subjects analysis of variance is calculated by dividing the sum of squares error (SSError) by the degrees of freedom for error, which is given by ab(n - 1) where a and b are the number of levels for the two factors, and n is the number of observations per cell. This formula accounts for the total number of observations contributing to the error term, adjusting for the structure of a two-factor design.
