Creating Box and Whisker Plots

In this video, Mr. Jay explains how to create box and whisker plots, also known as box plots, to visually represent data and its spread. The tutorial covers ordering data, identifying the minimum and maximum values, calculating the median, and determining the first and third quartiles. Finally, it demonstrates how to construct a box and whisker plot using these values, providing a clear visual representation of the dataset.

What is the primary purpose of a box and whisker plot?

• To calculate the mean of a dataset

• To determine the mode of the data

• To display data and its spread visually

• To plot the data on a bar graph
