Week 4 revision Flashcards
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
In a 3-way factorial ANOVA, identify the steps in following up an omnibus 2-way interaction
In a 3-way factorial ANOVA, identify the steps in following up an omnibus 3-way interaction
In a 3-way factorial ANOVA, explain what simple interaction effects are
What do simple interactions test
Why do we need simple interaction test
How are simple interactions tested
how are simple interaction tests different from omnibus 2-way interactions in a 3-way factorial design
how they are different from omnibus 2-way interactions in a 2-way factorial design
