Marathons and Medians – Graphics

Saw an article in the Wall Street Journal over the weekend about marathon runners and times. I love the graphics they use and the charts and tables and all. Did some poking around and couldn’t find their graphic online to look for copyright info and a place to request permissions to use their images. But, I did track down the data source (listed at the bottom of the article) as a website called Running USA and a place on their website where statistics and reports about the state of marathon races in the U.S. are posted. From that website, I noted data for Median Marathon Times and for Number of Finishers. The graphs and those data are listed below.

Ways to use these graphics include:

  • Ask students to identify the number of runners that finished a marathon in a given year.
  • Ask students the median time of marathons for males or females in a given year.
  • Ask students to generate a linear regression model for the median times and for the number of finishers then use those models for predictions.
  • Ask the students reasons why the median times are staying the same even though the number of runners in increasing.
  • And many more!

The data are public and my graphs are Creative Commons so use any way you want according to the licensing information below the images.
