1. Construct a complete, concise title for a line chart representing employment placement
rates for graduates in your major at your school from 2010 to the present. (LO2)
2. The chart prepared in Exercise 1 requires an explanation for the academic years 2011–2012
and 2012–2013. In each of those years, data were collected in January (mid-academic year)
rather than June (end of the academic year). Provide the necessary explanation. (LO6)
A footnote is appropriate here. It might appear as follows: “Data from 2011–2012 and 2012–2013
3. For each of the types of information described below, which form of visual would you use?
Explain your decision. (LO1–4)
a. Record of annual sales for Kenyon Company for the past 20 years.
b. Comparison of Kenyon Company sales, by product, for this year and last year.
c. Monthly production of the automobile industry in units.
Breakdown of how the average middle-income family in your state (or province) disposes of its
income dollar.
Comparison of sales for the past two years for each of B&B Company’s 14 sales districts. The
districts cover all 50 states, Canada, and Puerto Rico.
National production of trucks from 1950 to present, broken down by manufacturer.
Relationship between list price and gas mileage of alternative and gasoline-fueled cars.
Home purchases by home value, geographic region, and income.
A subdivided bar chart is a clear choice here. Regions would be represented by different colors.
The total number of home purchases for that region would be subdivided with a bar for income
ranges and a bar for home values. The bars would then be shaded to show the number of
purchases made in each range.
4. For each of the following sets of facts, (a) determine the visual (or visuals) that would be
best, (b) defend your choice, and (c) construct the visual. (LO1–5)

insurance) classification on one basis (income).
b. Profits and losses for Whole Foods Stores, by store, 2010–2014, in dollars.
