Sorting dot plots
EconViz Weekly has built a Big Mac price explorer for its global cost-of-living series. The dataset is the Big Mac Index (January 2020): the price of a McDonald's Big Mac in various countries. "Actual price" is the price converted to US dollars; "GDP adjusted price" has an additional correction for each country's gross domestic product.
As with box plots and bar plots, how you order the rows in a dot plot affects the kinds of questions that are easy to answer. Sorting alphabetically makes it easy to look up a specific country; sorting by price makes it easy to find the most or least expensive Big Macs.
Use the sort controls to explore different orderings, then determine which statement is true.
