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 s, and are useful tools in exploratory data analysis. Stemplots became more commonly used in the s after the publication of John Tukey 's book on exploratory data analysis in Modern computers' superior graphic capabilities have meant these techniques are less often used.
