Lesson 12

Using Mean and MAD to Make Comparisons

Lesson Narrative

In this lesson, students continue to develop their understanding of the mean and MAD as measures of center and spread as well as interpret these values in context. They practice computing the mean and the MAD for distributions; compare distributions with the same MAD but different means; and interpret the mean and MAD in the context of the data (MP2). 

Learning Goals

Teacher Facing

  • Compare (orally and in writing) the means and mean absolute deviations of different distributions, specifically those with the same MAD but different means.
  • Interpret the mean and mean absolute deviation (MAD) in the context of the data.

Student Facing

Let's use mean and MAD to describe and compare distributions.

Learning Targets

Student Facing

  • I can say what the MAD tells us in a given context.
  • I can use means and MADs to compare groups.
