Multiple Choice

Consider an experiment in which rats are given three diets (reduced calorie, control, and increased calorie) and their masses at 6 weeks of age are measured. Which of the following is an aspect of poor design in the figure shown?
​
​

• A) The different patterns for the groups provide no additional information because they are redundant with the labels.
• B) The figure is black and white; color is always better when making figures and graphs.
