Statistical charts and diagrams | Exploratory data analysis
A stem-and-leaf display or stem-and-leaf plot is a device for presenting quantitative data in a graphical format, similar to a histogram, to assist in visualizing the shape of a distribution. They evolved from Arthur Bowley's work in the early 1900s, and are useful tools in exploratory data analysis. Stemplots became more commonly used in the 1980s after the publication of John Tukey's book on exploratory data analysis in 1977. The popularity during those years is attributable to their use of monospaced (typewriter) typestyles that allowed computer technology of the time to easily produce the graphics. Modern computers' superior graphic capabilities have meant these techniques are less often used. This plot has been implemented in Octave and R. A stem-and-leaf plot is also called a stemplot, but the latter term often refers to another chart type. A simple stem plot may refer to plotting a matrix of y values onto a common x axis, and identifying the common x value with a vertical line, and the individual y values with symbols on the line. Unlike histograms, stem-and-leaf displays retain the original data to at least two significant digits, and put the data in order, thereby easing the move to order-based inference and non-parametric statistics.

Statistics - How to make a stem and leaf plot
This example shows how to make a stem and leaf plot. Remember that the leading values become our stems and the trailing values the leaves. There also may be more than one way to represent a stem and leaf plot. For more videos visit http://www.mysecretmathtutor.com

Both histograms and frequency tables have positives and negatives. Histograms portray the shape of the data but you lose the actual individual scores. Frequency tables retain individual scores in the table, but don’t show the shape of the distribution. But what if you want both? To get th
