Explanation:
Detailed explanation-1: -Mean absolute deviation (MAD) is a measure of the average absolute distance between each data value and the mean of a data set. Similar to standard deviation, MAD is a parameter or statistic that measures the spread, or variation, in your data.
Detailed explanation-2: -A small mean absolute deviation tells us that most of the data values are very close to the mean (since the expected distance from each data value to the mean is small). A high mean absolute deviation tells us that many of the data values are spread out further from the mean.
