2. To understand Mean Absolute Deviation, let us split both the words and try to figure out their meaning.'Mean' refers to the average of the observations and deviation implies departure or variation from a preset standard. When put together, we can define mean deviation as the mean distance of each observation from the mean of the data
3. It is also termed as mean deviation or average absolute deviation. It can be calculated by finding the mean of the values first and then find the difference between each value and the mean. Take the absolute value of each difference and find the mean of the difference, which is termed as MAD. Find the MAD of a data set using this mean absolute.
4. The mean deviation is a measure of dispersion, A measure of by how much the values in the data set are likely to differ from their mean. The absolute value is used to avoid deviations with opposite signs cancelling each other out. Mean absolute deviation formula. This calculator uses the following formula for calculating the mean absolute.

The median absolute deviation is a measure of statistical dispersion. Moreover, the MAD is a robust statistic , being more resilient to outliers in a data set than the standard deviation . In the standard deviation, the distances from the mean are squared, so large deviations are weighted more heavily, and thus outliers can heavily influence it Note: the mean deviation is sometimes called the Mean Absolute Deviation (MAD) because it is the mean of the absolute deviations. What Does It Mean ? Mean Deviation tells us how far, on average, all values are from the middle. Here is an example (using the same data as on the Standard Deviation page)
