Benchmarking Exercise
PA 200 – The Urban Scene Dr. Robert J. Sobie
Benchmarking Exercise Using the data provided in Table 1, construct a histogram (aka bar chart)1 that visually compares one‐ way daily commute time for several U.S. cities. According to the U.S. Census Bureau (2013), the average one‐way daily commute time is 25.5 minutes. This average may or may not be considered a national “best,” for commuting to work so let’s assume 23.2 minutes is.
Which of the cities are above and below the national average (25.5)?
Which of the cities are above and below the “assumed” best practice (23.2)?
Are there any differences between the cities that might influence the variation in commute times? If so, briefly explain in one or two paragraphs.

1 Ideally, you would use Microsoft Excel to construct the histogram. If, however, you’re not familiar with Excel, feel free to use a drawing tool (like Microsoft Word or Publisher, or even PowerPoint) to arrange shapes (bars, lines) and headings together to create the chart. Of course, you can always hand draw the chart as well.
Submit your completed benchmarking chart and brief explanation by the stated due date/time on Blackboard.
