Plotting numeric variables shows us interesting characteristics of our data. In this video we’ll explore pulse rates and household incomes and learn how to describe what we see.
After you’ve watched this video, you should be able to answer these questions How is a stacked dot plot constructed? What are the four types of things we look for in dot plots? What is the common name for the mean? How does the mean relate to the dot plot? What property defines the median? When do the mean and median tend to be very similar, and when can they be quite different? Why might we prefer the median to the mean for personal incomes?
