Introductory Stata 38: Graphs For Single Continuous Variable (Box plot)

The box plot highlights several statistics of the distribution of a single continuous variable. The median is the line inside the box. The 25 percentile and the 75 percentile are at the edge of the box. At the end of the whiskers are the minimum or maximum values. But if there are outliers in the data, it would be the adjacent value. It is 1.5 times the interquartile range away from the edge of the box.
Let's continue to use the dataset for the US workers. You can download it from the link below.
