MODULE 6 DISCUSSION

INSTRUCTIONS

Research Example

1. Provide an example of research you would be interested in conducting that requires you to examine differences between three or more groups on some outcome. (A group of psychiatric patients are trying different therapies:)

2. Now assume that you were going to add a third variable to your model. What would this variable be?

3. Explain why you selected this third variable and explain if you would perform an ANCOVA or two-way ANOVA.

· Your initial post (approximately 200-250 words) should address each question in the discussion
