Computer Program for Stem-and-Leaf Diagram

Abstract

The stem-and-leaf diagram represents a useful statistical process control tool. This graphical display provides information about the shape, variability, and central tendency of the measurements’ distribution. The paper presents a computer program that can be used for plotting three variants of the stem-and-leaf diagram. The first variant plots the regular stem-and-leaf diagram, the second one plots the diagram with the stems divided into two parts, and the last one plots the diagram with the stems divided into five parts. The presented program can be used in scientific research and in plant practice for obtaining information about the measurements’ distribution.
