This activity aims to build an understanding that Mean Absolute Deviation (MAD) is used to measure variance. It allows students to start informally by estimating MAD visually prior to formally calculating MAD.
This activity provides an exploration of the meaning and process of mean absolute deviation. At the end of the lesson there is a slide that can be used for any data set (with `\le12` data points) to walk students through the process step-by-step, giving feedback for any errors along the way.
This worksheet works best to reinforce mean absolute deviation (MAD). Make sure that students bubble in their answers for the front page (#1-7) and the back page (#8-14). The bubbles allow students to check their answers and results in a more confident student.
This calculator uses the following formula for calculating the mean absolute deviation: where n is the number of observed values, x-bar is the mean of the observed values and x i are the individual values. Online calculator to compute the mean absolute deviation from a set of values.

Solving Absolute Value Equations (Algebraically) • Activity Builder by Desmos Classroom. Loading...
Students will review the definition of absolute value, interpreting it as distance, and solving basic absolute value equations with number lines. I had students paired with one iPad and kept us together using teacher pacing.
