The figure shows the population density (people per square mile) for the 50 states in the United States, based on an estimate from the U.S. Census Bureau. The regions are the Midwest (MW), Northeast (NE), South (S), and West (W). In the West, the potential outlier is California, and in the South, the potential outlier is Maryland.
Why is it best to compare medians and interquartile ranges for these data, rather than comparing means and standard deviations? List the approximate median number of people per square mile for each location; for example, the median for the MW is between 50 and 100. Also arrange the regions from lowest interquartile range (on the left) to highest.
