Exploratory Data Analysis: Stem-and-Leaf Displays

In this video I explain stem-and-leaf displays or stemplots, which are part of exploratory data analysis developed by John W. Tukey. I explain the basic design of stem-and-leaf displays as well as several variations including back-to-back stem-and-leaf displays and stretched stem-and-leaf displays. I also discuss the role of rounding and cutting data when dealing with large numbers or decimals, and the usefulness of more complex stem-and-leaf displays for storing data.
