It is an online statistical calculator for the easy calculation of the mean absolute deviation. From the name itself it is clear that mean absolute deviation is the absolute value of deviation from the mean. The expression is mentioned below.
MAD= $\frac{1}{n}\sum_{i=1}^{n}\left | x_{i}-\bar{x} \right |$

Where n is the total number of observations
           $x_{i}$ is the observations
           $\bar{x}$ is the mean
Following steps are used to find out the mean absolute deviation.

Step1: Note down the given observation from the question.

Step2: Find out the mean of the given values using the equation.

Step3: Using the following equation, calculate the mean absolute deviation.
MAD= $\frac{1}{n}\sum_{i=1}^{n}\left | x_{i}-\bar{x} \right |$
