Learning Objective

I can calculate and interpret the five number summary, range, and interquartile range of a data set.

  • 1

    The five-number summary includes the minimum value, first quartile (Q1), median (Q2), third quartile (Q3), and maximum value.

  • 2

    The quartiles divide a data set into four equal parts, where Q1 is the 25th percentile, Q2 is the 50th percentile, and Q3 is the 75th percentile.

  • 3

    The range is the difference between the maximum and minimum values, while the interquartile range (IQR) is the difference between Q3 and Q1.
