The Mean Absolute Deviation (MAD) is a measure of the average absolute distance between each data value and the mean of a data set. It is a summary statistic of statistical dispersion or variability. The MAD can be calculated using the following steps:
- Calculate the mean of the data set.
- Calculate the absolute deviation of each data point from the mean (the absolute value of the difference between the data point and the mean).
- Add up all the absolute deviations.
- Divide the sum of the absolute deviations by the number of data points.
The formula for calculating the MAD is:
$$ MAD = \frac{\sum...
