A *five-number summary* of data is a concept that is commonly used in statistics. It consists of the first quartile (Q_{1}), the median, the third quartile (Q_{3}), and the largest and smallest number of the data. The *five-number summary* is written in smallest to largest form. It is written in the following format:

Smallest #, First Quartile, Median, Third Quartile, Largest #

Using the numbers 1-15 as our data, the *five-number summary* would look like the following:

1 4 8 12 15
