This video tutorial introduces box and whisker plots, explaining their components and how they visually represent data. It provides practical examples using commercial break data and gumball weights to demonstrate how to construct and interpret these plots. The tutorial highlights the importance of understanding quartiles, medians, and outliers in data analysis, and how box plots can simplify complex data sets for easier interpretation.

What does the rectangular region in a box and whisker plot represent?

• The range of the data

• The median of the data
