# What Is The Mean Absolute Deviation In Math?

Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean. Mean absolute deviation is a way to describe variation in a data set. Mean absolute deviation helps us get a sense of how "spread out" the values in a data set are. Google Classroom Facebook Twitter

## How is the mean absolute deviation ( MAD ) related to the mean?

The Mean Absolute Deviation (MAD) of a set of data is the average distance between each data value and the mean. The mean absolute deviation is the "average" of the "positive distances" of each point from the mean. The larger the MAD, the greater variability there is in the data (the data is more spread out).

## How is the deviation from the mean calculated?

It tells us how far, on average, all values are from the middle. In that example the values are, on average, 3.75 away from the middle. For deviation just think distance Each distance we calculate is called an Absolute Deviation, because it is the Absolute Value of the deviation (how far from the mean).

## Which is the best definition of absolute value?

absolute value. - the distance (a positive quantity) of any value on a number line from zero. - the sum of the absolute values of deviations on each side of the mean are equal. variability. - refers to how spread out (or clustered together) the values are in a data set. - high variablity means the data is spread out.
