The document discusses box and whisker plots, which are diagrams that display data through their minimum, maximum, quartiles, and median values. It provides examples of box plots using sample data sets and explains how to find the minimum, maximum, median, first quartile, and third quartile values. Finally, it gives homework instructions for students to create their own box plot using a data set collected from at least 11 people on a chosen topic like daily water consumption.
