The mean absolute deviation is a measure of variability in statistics. This number tells us how close the rest of the numbers are to the mean. The closer they are to the mean, the more reliable the data is.
The attached work shows how to find the MAD (mean absolute deviation).
Here are the steps:
1. Find the mean of the data. 2. Find the difference between the mean and the data values. 3. Find the average of these differences.
