You run a Mixed ANOVA to investigate the potential benefits of three different diets (raw; ketogenic; caloric control) across time (participants weighed themselves once before starting the diet, and then once after completing their set 4-week plan). However when it comes time to run your analysis, in your screening tests you encounter the output below. What does this screening test indicate? Mauchly's Question 10Select one: a. Sphericity is very important because we have a within-subjects independent variable, and this output indicates that we must report the Greenhouse-Geisser line in subsequent outputs because Mauchly's W is greater than 1. b. Sphericity is very important because we have a within-subjects independent variable, and this output indicates that we must report the Huynh-Feldt line in subsequent outputs because Mauchly's W is greater than 1. c. Mauchly's test is not relevant here. d. We have made an error in defining our repeated-measures in SPSS
