An Introduction to Boxplots

An introductory to boxplots. (I do not carry out any calculations, this video is about interpreting boxplots.) I discuss the basics, an applied example, give a few illustrations of histograms and boxplots under symmetry and skewness, then briefly discuss how large samples often lead to a large number of outliers in a boxplot.
