Creating and Analyzing Stem-and-Leaf Plots

This video tutorial introduces the concept of stem-and-leaf plots, a data distribution method taught in fourth grade. It explains how to create and analyze these plots using a set of random numbers. The tutorial also covers advanced examples, including the use of mixed numbers in stem-and-leaf plots, demonstrating their versatility in representing data.
