# Lesson Plan: Box-and-Whisker Plots Mathematics • 6th Grade

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to construct and analyze data from box-and-whisker plots.

#### Objectives

Students will be able to

• construct a box-and-whisker plot of a data set (with and without an outlier) when given the lowest or highest values, the lower or upper quartiles, and the median,
• identify the upper and lower quartiles, the range, the median, and the IQR from a given box-and-whisker plot,
• compare and contrast the center and spread of two data sets when given their box-and-whisker plots within the same grid,
• construct a box-and-whisker plot from a raw data set.

#### Prerequisites

Students should already be familiar with

• the range,
• the lower and upper quartiles,
• the median,
• the IQR,
• the 1.5 IQR rule for outliers.

#### Exclusions

Students will not cover

• problems not involving box-and-whisker plots,
• determining the skewness of a distribution from the box-and-whisker plot.
