Middle Grades Math: Interrogating Data by Random Sampling

Objectives

• Students will use box plots and histograms to analyze data.
• Students will use data from a random sample to draw inferences about an unknown characteristic of interest that describes a population.

Vocabulary

• mean
• population
• random sampling
• histogram
• Mean Absolute Deviation (MAD)
• median
• sample
• box plot
• Interquartile Range (IQR)

About the Lesson

This lesson involves using random sampling to make predictions about a population.
As a result, students will:

• Use box plots, histograms and measures of central tendency to draw inferences about samples and a population.
