Below are general types of ANOVA designs we will be reading about in this module. The differences in methodology are based on experimental design:
- One-Way Between-Subjects or Within-Subjects Design
- Two-Way Between-Subjects Factorial Design
We discussed the pros and cons of one-way between-subjects ANOVA and one-way within-subjects ANOVA in Module 6. Use some of those facts discussed in that last discussion and debate the advantages and disadvantages of one-way ANOVA designs vs two-way factorial ANOVA designs with your classmates. Summarize the advantages and disadvantages of each from a statistical and practical perspective, and provide a real-world example of an experiment and design for the two-way factorial ANOVA.
Use your real-world example to explain in detail, how the example you provided fits the design selected for that example (two-way between-subjects factorial design). Make sure to discuss your:
- Experimental design
- Sample size
- Number of variables
- Number of levels for each variable
- Possible interactions between variable
