3.49 Thinking critically about a graph of international students: Researchers surveyed Canadian students on their perceptions of the globalization of their campuses (Lambert & Usher, 2013). The 13,000 participants were domestic undergraduate and graduate students—that is, they were not recently from countries outside of Canada. The pie chart here shows the responses to one survey item: “The increasing number of international students attending my institution has led to improvements in the university’s reputation and image.”

a. What is the story that these data are telling?

b. Why would a bar graph of these data tell this story better than a pie chart does?

c. Create a bar graph of these data, keeping the bars in the order of the labels here—from “Strongly disagree” on the left to “Not sure/don’t know/N/A” on the right.

d. Why would it not make sense to create a Pareto chart in this case?
