The former include drawing a stem-and-leaf plot, scatterplot, box-plot, histogram, probability-probability (P-P) plot, and quantile-quantile (Q-Q) plot. A Stata user may then keep the rst, last, or any specied observation within the grouping, dropping the others.> boxplot( pretest, posttest, notchTRUE ).

Below, we show the boxplots for vehicle price based on origin (US or non-US)This section describes the procedures in Stata that test the equality of means of a continuous variable from two or more groups. That ensures that each box plot will be the same size. By specifying holes, we persuade graph box to put graphs on two rows.For even more flexibility, you may need to abandon graph box and use twoway instead.
