Describing Data Distribution with Mean Absolute Deviation

This lesson explains how to describe data distribution using mean absolute deviation (MAD). It begins with a review of calculating the mean and understanding absolute value. The lesson then details the steps to compute MAD, using examples to illustrate the process. A second example demonstrates MAD calculation with a different data set, highlighting how MAD indicates data spread. The lesson concludes by summarizing the key points about MAD.

What is the mean of a data set and how is it calculated?

Explain the concept of absolute value and provide an example.

What is the difference between mean and mean absolute deviation?

How do you find the mean absolute deviation from a set of numbers?

What does a mean absolute deviation of 3 and 8/10 indicate about a data set?
