Question

Quizplus · Accepted Answer

A factorial design with two independent variables requires a two-way ANOVA to evaluate the data. This allows for the examination of main effects for each independent variable as well as their interaction effect. Choice A, one-way ANOVA, is not appropriate for a design with two independent variables. Choice B, t test for independent groups, is appropriate for comparing means of two independent groups, but not for examining the effects of two independent variables. Choice C, t test for matched groups, is appropriate for comparing means of two groups that are matched, but not for examining the effects of two independent variables.
