What are higher order designs
What research questions do higher order designs adress?
Why are higher order designs useful?
Indicate the general and specific notations for a factorial design with:
Factor A (with 2 groups/levels),
Factor B (with 4 groups/levels),
Factor C (with 3 groups/levels)
Identify the different omnibus effects that may be found in 3-way factorial ANOVA, and explain
what research questions are addressed with each
How are three way interactions graphed?
How is variance partitioned in a three way anova?
What is the structural model for a 3-way ANOVA?
what is the formulae for all degrees of freedom in 3-way factorial ANOVA?
In the omnibus summary table for 3-way factorial ANOVA, explain what the SS and MS values
represent, and how F is calculated for each effect
In a three way factorial ANOVA what does a significant F test for the main effect of Factor A mean?
In a three way factorial ANOVA what does a significant F test for the A x B 2-way interaction?
In a three way factorial ANOVA what does a significant F test for the A x B x C 3-way interaction?
In a 3-way facorital ANOVA what are the circumstances you would follow up a main effect, omnibus 2-way interaction, and an omnibus three-way interaction?
In a 3-way factorial ANOVA, identify the steps in following up an omnibus main effect
