Ratfactorial: Effect of a protein on weight gain in rats

Description Usage Format Source

Description

The Ratfactorial dataset contains data from an experiment to study the effect of six different diets on the gain in weight of rats. Each diet was at either high or low protein (factor Amount), and the protein was derived from either beef, cereal or pork (factor Source). A completely randomized design was used, with 60 rats allocated at random, 10 to each treatment.
