The GHOST Box Plot – Mini Paper Appearing in Summer 1988 Newsletter

Abstract: The box plot (a.k.a. box-and-whisker plot) is a simple and powerful tool for exploratory data analysis (EDA). The box plot is simple to construct and interpret. It provides a way of organizing and summarizing groups of data. Furthermore it facilitates communication between practitioners thanks to its visual characteristics. This paper introduces the GHOST Box plot, a box plot that is superimposed at the middle of a x-y time series plot of measurement data from a process. This technique gives the practitioner an overall "batch" view of the data set.
