Each March, the Bureau of Labor Statistics compiles an Annual Demographic Supplement to its monthly Current Population Survey. Data on about 71,067 individuals between the ages of 25 and 64 who were employed full-time were collected in one of these surveys. The parallel boxplots compare the distributions of income for people with five levels of education. This figure is a variation of the boxplot idea: because large data sets often contain very extreme observations, we omitted the individuals in each category with the top 5% and bottom 5% of the incomes. Also, the whiskers are drawn all the way to the maximum and minimum values of the remaining data for each distribution. One of the trends evident in this graph is that individuals with more education tend to attain jobs that yield more income.
