Abstract
Studying distributions of quantitative traits plays a special role in data analysis; the best tools for that purpose appear to be graphical methods. Among various types of plots, most important ones are histograms, density plots and box-plot. In this paper, we introduce a less frequently applied stem-and-leaf diagram, which is a graphical-tabular technique of data visualization. This simple and interesting technique, despite its simplicity, can provide quite deep information about a variable’s distribution. To present how the stem-and-leaf display works, we have used R environment.
