## Box Plots & Histograms

#### Activity Overview

Students create and explore a box plot and histogram for a data set. They then compare the two data displays by viewing them together and use the comparison to draw conclusions about the data.

#### Key Steps

• In the first part of the activity, students are given a scenario. They use the data supplied to discuss any visible trends when studying the data.

• Students create a box plot from the data in the spreadsheet. They will analyze the different sections of the plot and determine where the mean falls relative to the median.

• In the second part of the activity, students use the same data to create a histogram. They study and manipulate the histogram to gather information about the data. They explore the relationship of the mean and median by plotting both values.
