Editing Stem-and-leaf display (section)

==Usage==
Stem-and-leaf displays are useful for displaying the relative density and shape of the data, giving the reader a quick overview of the distribution. They retain (most of) the raw numerical data, often with perfect integrity. They are also useful for highlighting [[outlier]]s and finding the [[mode (statistics)|mode]]. However, stem-and-leaf displays are only useful for moderately sized data sets (around 15–150 data points). With very small data sets a stem-and-leaf displays can be of little use, as a reasonable number of data points are required to establish definitive distribution properties. A [[dot plot (statistics)|dot plot]] may be better suited for such data. With very large data sets, a stem-and-leaf display will become very cluttered, since each data point must be represented numerically. A [[box plot]] or [[histogram]] may become more appropriate as the data size increases.
