BOXPLOT Procedure


The BOXPLOT procedure creates side-by-side box-and-whiskers plots of measurements organized in groups. A box-and-whiskers plot displays the mean, quartiles, and minimum and maximum observations for a group. The procedure enables you to do the following:

  • control the style of the box-and-whiskers plots
  • specify one of several methods for calculating quantile statistics (percentiles)
  • add block legends and symbol markers to reveal stratification in data
  • display vertical and horizontal reference lines
  • control axis values and labels
  • overlay the box plot with plots of additional variables
  • control the layout and appearance of the plot
