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.
