- Which is the most striking feature of a two-factor ANOVA?In two-way ANOVA, the interaction effect tests whether the effects of one Independent Variable are uniform for all groups of the second Independent Variable. Is the underlined statement True or False? True FalseThink of a research scenario for which either 1-way or 2-way ANOVA would be needed to analyze the results.
- In a two-way ANOVA, why is the test for interaction done first?If no main effects emerge in a two-factor ANOVA, there must also be no significant interaction between the two factors. Group of answer choices True FalseExplain the difference between the one-way fixed effects model and the one-way random effects model.
