Two-Factor / Quasi-Experimental Designs Flashcards
Analysis, Interaction Effects etc.
1
Q
Features of Two-Factor Designs
A
- Two IVs
- Each factor has 2+ levels
- Experimental or quasi-experimental
- Interaction effect may be present
2
Q
When would a two-way mixed ANOVA be used?
A
- 1 Repeated Measures and 1 Independant Groups Factor
3
Q
When would a two-way Repeated Measures ANOVA be used?
A
- Repeated Measures
- Two Factors
4
Q
When would a two-way Independent Groups ANOVA be used?
A
- Independent Groups
- Two Factors
5
Q
When would a Simple Main Effects Analysis be conducted?
A
Significant INTERACTION EFFECT
(2+ Factors needed)
6
Q
What is an interaction effect?
A
The effect of one variable depends on the level of one or more variables
7
Q
How are two-factor designs interpreted?
A
- Effect of A
- Effect of B
- Interaction Effect : A x B
8
Q
When would you conduct pairwise comparisons?
A
When a significant effect is present but this isn’t an interaction effect
