Creating 3-Digit Stem-and-Leaf Plots

This video tutorial by Mr. J explains how to create a stem and leaf plot to organize and display data. It covers the steps of ordering data, creating the plot with stems and leaves, and finalizing it with a key and title. The example used involves the number of packages delivered per day over 20 days, with data ranging from 194 to 240. The tutorial emphasizes the importance of ordering data and provides a clear method for splitting numbers into stems and leaves.
