Box and Whisker Plot

This guide walks you through the steps to create a Box and Whisker plot using a set of numerical data. You will learn how to order the numbers from least to greatest, identify the lower and upper extremes, and plot them on a number line. Additionally, you will find the median and the quartiles of the data set. The provided data includes a mixture of values, and by following the outlined steps, you will be able to visualize the distribution effectively via a Box and Whisker plot.
