Exploring Stem and Leaf Plots

The video tutorial introduces the concept of stem-and-leaf plots, demonstrating how to organize data using this method. It provides an example involving video game playtime data, showing how to arrange the data and create a stem-and-leaf plot. The tutorial also covers calculating statistical measures such as mean, median, mode, and range using the organized data. The video concludes with a practice problem for viewers to try on their own.
