What does a fair wealth distribution look like? In the United States, 10% of families own more than 70% of the total wealth. In other places, though, the wealth distributions looks very different...for both good and ill.

Students use mean, median, histograms, and box-and-whisker plots to compare how wealth is distributed in different countries and debate the pros and cons of their ideal distribution.

Students will

  • Calculate mean and median; determine which measure of central tendency is most appropriate
  • Interpret and create box-and-whiskers plots

Before you begin

Students should be able to calculate the mean and median of a small data set. They should also be able to find quartiles and use them to construct a box plot to summarize data.
