Mean deviation

Now Let us start learning with mean deviation in math. This writing will give you some usefule information to how to solve math problem

The mean deviation of a statistical information is defined as the arithmetic mean of the numerical values of the deviations of items from some average value.

The difference between observed value & the expected value of a function is called mean of deviation. The mean deviation is the mean of the absolute deviation of a set of information about the data's mean. It is an important expressive statistic that is not often used in mathematical statistics. This is fundamentally mean deviation as the "mean deviation from the mean," the introduction of the whole value makes logical calculations using this statistic much more difficult.

Mean deviation is also called average deviation.

The mean deviation is usually denoted by M.D.
