MAD can be used for skewed distributions, but it may not provide an accurate representation of the data spread. For skewed distributions, it's often better to use alternative measures, such as the Interquartile Range (IQR).
The result is the Mean Absolute Deviation, which indicates the average distance between each data point and the mean.
Using MAD in data analysis offers several benefits, including:

Common Questions About Mean Absolute Deviation
While both MAD and Standard Deviation measure data spread, they differ in their approach. Standard Deviation is a more sensitive measure, as it is affected by extreme values in the dataset. MAD, on the other hand, is more robust and provides a better representation of the typical deviation from the mean.
