Part II. After assessing the participants' baseline BMI, the researcher then prescribes all participants the same calorie-balanced dietary program for 24 weeks. The researcher then reassesses each participant's BMI at 12 weeks (mid-treatment) and 24 weeks (post-treatment) to determine whether the calorie-balanced dietary program yielded changes in the participant's BMI over the 24-week period. Assume that the researcher is not interested in exploring the between group effects in BMI for this part of the assignment and use the JASP data file provided to perform and answer questions for a repeated measures AN OVA. 1. What is the research question? Why is a one-way repeated measures ANOVA appropriate to answer this research question? 2. Provide a statistical, symbolic, and substantive hypothesis for the research study. 3. Choose an a priori alpha level and designate whether the test is 1tailed or 2-tailed. 4. List and operationally define the variables. Which variable(s) is independent? Which variable(s) is dependent? How many levels does the independent variable have and what are they? What are the levels or scales of measurement for the variables? 6. Compute an a priori power analysis with G*Power. Please take a screenshot of your analysis and include it with your submission of the assignment. 7. What are the basic assumptions for a one-way repeated measures AN OVA? Do the data meet these basic assumptions? Why or why not. 8. Create a histogram for the dependent variable. Do the data have any outliers or extreme values? 9. Has the basic assumption of sphericity been met? How do you know? 10. If sphericity has been met, which line on the \"Tests of Within-Subjects Effects\" should we review? If sphericity is was not met, which line should we review? 11. Is there a main effect for any of the variables? An interaction effect? If there is an interaction effect, what should we do with the main effect? 12. If a significant F ratio is found, what should we do to determine where the differences occurred? .0"
