Question

The book The Wall Street JournalGuide to Information Graphics by Dona M. Wong gives strategies for using graphs and charts to display information effectively. One popular graph discussed is the donut pie chart. The donut pie chart is simply a pie chart with the center removed. A recent Harris Poll asked adults about their opinions regarding whether books should be banned from libraries because of social, language, violent, sexual, or religious content. The responses by education level to the question "Do you think that there are any books which should be banned completely?" are shown in the following donut pie charts.

(a) What feature of Keith's graph makes it difficult to visually compare the responses of those with some college to those shown in the other graphs? (Select all that apply.)

a)The graphs made by Keith and Ramon compare groups across education level.
b)The graphs made by Keith and Ramon are all donut pie charts.
c)The graphs do not have data labels showing the percentages.
d)The donut hole in the graph made by Keith is a different size than in the graphs made by Ramon.
e)The graphs made by Keith and Ramon use the same colors for each of the corresponding responses.



How would you change Keith's graph for easier comparison? (Select all that apply.)

a) Add data labels showing the percentages.
b)Change the graphs from donut pie charts to time series graphs.
c)Use different sets of colors in each of the donut pie charts.
d) Make all donuts exactly the same size, with the radius of the holes the same as well.
e)Combine the graphs into one donut pie chart.



(b) Compare graphs made by Ramon. At which of the two education levels is the "no" response more frequent?

High school or less
Some college    
College graduate
