In this lesson, you'll learn how to calculate the five number summary of a set of data values. This includes the maximum and minimum values, the median, and the upper and lower quartiles. The quartiles divide the data set into quarters, making it easier to interpret and visualize. The interquartile range is a better measure of how spread out your data is than the range, and the box and whisker plot is a useful visual representation of the distribution of your data.
