Explanation:
Detailed explanation-1: -The mean absolute deviation (MAD) is a measure of variability that indicates the average distance between observations and their mean. MAD uses the original units of the data, which simplifies interpretation. Larger values signify that the data points spread out further from the average.
Detailed explanation-2: -MAD, i.e., mean absolute deviation tells us about the spread of data from its mean. Simply, it is a measure of variability among the data values. So, the more MAD, the more variability.
