DATA SET: Diet SPSS Data File DESCRIPTION: A randomized controlled trial was conducted to examine the relationship between diet and weight loss among adults. A convenience sample of 78 participants were randomized to one of three treatment groups: (a) low carbohydrate diet, (b) low fat diet, or (c) Mediterranean diet. Demographic characteristics included gender and age. Height and weight were measured at baseline and weight was measured again at the end of the 12-week dietary intervention period. The primary research question that investigators sought to answer was: Among three leading diets, which one was best for weight loss? The research plan called for limiting the probability of making a Type I error to 5%. Answer the following questions about the primary research question. What is the independent (grouping) variable? What is the level of measurement for the independent variable? What is the dependent (outcome) variable?
