Understanding Stem-and-Leaf Plots

The video tutorial introduces dot plots and stem and leaf plots, explaining their components and uses. It provides an example of a dot plot showing goals per game and calculates the total goals scored. The tutorial concludes with a discussion on data distribution and skewness, highlighting how most data is skewed towards the high end.
