Low-carb versus low-fat. Researchers conducted an experiment to compare the effects of a carbohydrate-restricted diet (low-carb diet) and a calorie- and fat-restricted diet (low-fat diet) on weight loss. The researchers are concerned that the effect of diet may depend on gender, so sex is treated as a blocking variable. There are 122 severely obese individuals available for the study, 52 of whom are men and 70 of whom are women. Use a diagram to outline a block design for this experiment. Use Figure 6.2 as a model.
