Reflection 10 #1 – On reflection 6 you should have created your own hypothesis. Now let’s assume that you received a green light to go on with your study.
Based on your hypothesis, how could you design a study that compares three groups? They can be the same subjects compared three different times or they can be three different groups compared once. For example, if I’m interested on whether a college degree affects income, I would gather a group of college graduates with a Bachelor’s degree and gather data on how much money they make; then I would compare them with a group of college graduates with a Master’s degree and a group of college graduates with a PhD.
In your case, first recall what your null and alternative hypotheses are. Then explain how you would test this hypothesis with three groups of subjects.

If you have three groups of subjects then you would compute an ANOVA.
If it’s the same subjects tested three times, then is called a within-subjects ANOVA.
If it’s three different groups tested once, then is called a between-subjects ANOVA.
