A study was conducted to evaluate the effects of weight gain in rats. Four diets were considered, which differed in: (1) the amounts of protein (high and low), and; 2) the source of the protein (beef versus cereal). Data in each column show the weight gain in individual rats after being fed the respective diet for a time period.
