Box and Whisker Plot Concepts

The video tutorial explains how to create parallel box and whisker plots to compare data sets. The instructor uses data from two sons' iPad usage to demonstrate sorting data, calculating medians, quartiles, and interquartile ranges. The video concludes with a comparison of the two data sets, highlighting differences in data spread and usage patterns.
