*Box Plot:*

For visualizing data, there is a **Graphical Representation** of a **5-number summary** called a **Box Plot,** or **Box and Whisker Graph.**

*Creating a Box Plot:*

To create a **Box Plot,** a **number line** is first drawn. A box is drawn from the *first quartile* to the *third quartile,* and a line is drawn through the box at the **Median.** **“Whiskers”** are extended out to the **minimum and maximum** values.

While quartiles are not a 1-number summary of variation like **Standard Deviation,** the *quartiles* are used with the **Median, Minimum, and Maximum** values to form a **5 number summary** of the data.

*Five number summary:*

The five number summary takes this form:

**Minimum, Q _{1}, Median, Q_{3}, Maximum**

**Hook questions:**

*1. What is Box and Whisker Graph?*
