Exploring Box and Whisker Plots
Learning Objective
I can create and interpret box and whisker plots to analyze data sets.
Key Concepts
A box plot displays the minimum, lower quartile, median, upper quartile, and maximum values of a data set.
The range is the difference between the maximum and minimum values, while the interquartile range (IQR) is the difference between the upper and lower quartiles.
The interquartile range (IQR) measures the variability of a data set; a larger IQR indicates more variation in the data.
