In statistics, median absolute deviation (MAD) is a reliable measure of the variability of a univariate sample of quantitative data. It can also often refer to the collective parameter.The volume, which is estimated only using the MAD, calculated on the basis of a significant sample.
For a one-dimensional dataset X 1 , X 2 , …, X n , the exact MAD is defined as typical of absolute deviations new data median :

that is, if toxins (outliers) start at the median of the data, MAD is the median of their absolute values.
Example
Consider dates (1, one specific, 2, 2, 4, 6, 9). It has a median value of 6. Absolute deviations around 2 will almost certainly be 1 (1, 0, 0, 2, 3, 7), which in turn has a corresponding median value of 1 (since these sorted absolute deviations are (0, zero, 1, 1, 2, 4, 7)). Thus, the mean absolute deviation for such data is 1.
Usage
Average absolute change is a measure of statistical dispersion. Also, MAD isa more reliable statistic that is more robust when you need outliers in the dataset than a fraction of the standard deviation. In the case of the standard difference, the distances to the mean have been squared so that larger deviations are measured more strongly and therefore outliers can have a strong impact. In MAD, the deviations of a small number of outlier cells are undoubtedly insignificant.
Because MAD is a more reliable means of estimating within sample variance or standard deviation, it works best in addition to distributions with no mean or editing, such as the Cauchy distribution.
Ratio To Standard Deviation
MAD can be selected in the same way as if it supports the average spread.Agree to use MAD as a daily estimator to estimate the standard deviation
How do you calculate the median absolute deviation?
Step 1: find the median. The median for this number is 8. Step 2: Subtract the median of each x-value using the formula | y i – median |. Second step: find the median value of the absolute arguments.

we can get this , which received the scale factor .
.Another way to establish a relationship is with a MAD equal to half the normal median delivery value:

In the same way that this median is generalized to the multidimensional data of the last geometric median, it is possible to construct a geometric MAD that unambiguously generalizes the MAD. In the case of two dimensional data recording with a partner (X 1 , Y 1 ), (X 2 , Y 2 ), …, (X n , Y n ) and just a typical geometrically calculated 
This gives the same result as all 1D 1D MADs and is easy to apply to higher dimensions. For real complex values (X + iY), the ratio of MAD to frequency does not change for commonly reported data.
Population MAD
The MAD population is well defined, similar to the MAD sample, but based on full distribution rather than experiment. If the distribution is symmetrical to the mean, the population’s MAD corresponds to that particular 75th percentile of the distribution.
What does the median absolute error metric say about the regression?
This is because it is also the median of most of the absolute residuals, and the values at some ends do not affect the overall median. Thus, this loss function can be used more to perform robust regression.
Unlike variance, which can be infinite or indefinite, the MAD of a population is definitely a finite number. For example, this standard rubber has an undefined distribution.division, but its MAD is 1.
This term was first used in connection with MAD in 1816 in connection with the work of Karl Friedrich Gauss on determining the accuracy of digital observations. [4] [5]

What does the median absolute deviation tell you?
Mean absolute deviation (MAD) is the simplest method to quantify variation. Regardless of whether the value is above or below the median, think of the men and women between it and the median as another positive value (in mathematical terminology, you take a fraction of the absolute value of the difference between your current value and the median).
What does median absolute deviation tell you?
The overall mean deviation (MAD) is a reliable measure of the correct distribution of a series of ratios. It is less affected by outliers because outliers have less impact on the median than on the mean. The term “mean absolute deviation” refers to statistics calculated from a specific sample.

What does median absolute deviation tell you?
The mean gross deviation (MAD) is a reliable measure of the spread of the supply in the direction of the data. Outliers affect a smaller amount because outliers have less impact on the type than recommendations. The term “mean absolute deviation” refers to statistics calculated from a large sample.
