Very often, in engineering investigations, the eects of two or more factors are considered simultaneously. The two-away ANOVA deals with the case where there are two factors. • Two-way analysis of variance (ANOVA) is used to compare population means when populations are classified according to two factors. ANOVA assumes that the populations are Normal and that independent SRSs are drawn from each population. The populations may have different means SPSS Conjoint™ performs conjoint analysis.
