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.
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.
Is Wheel of Fortune rigged? Students use percents and probabilities to compare theoretical versus experimental probabilities, and explore whether the show is legit, or whether there might be something shady going on!

Should shoe companies sell left and right shoes separately? Students collect survey and measurement data, construct bar graphs, and discuss distributions and measures of central tendency in order to figure out whether shoe companies should necessarily be selling their products in same-size pairs.
How have video game consoles changed over time? Students create exponential models to predict the speed of video game processors over time, compare their predictions to observed speeds, and consider the consequences as digital simulations become increasingly lifelike.
