The mean absolute deviation is the summation of the absolute value of each deviation. The formula for MAD is 1n(∑limits_(i=1)^n x_i-μ) where n= the number of items in the data set, X_i= the i^(th) number in the data set, and μ= the mean of the data set. For example...
The mean absolute deviation is the summation of the absolute value of each deviation. The formula for MAD is where n= the number of items in the data set, the number in the data set, and the mean of the data set. For example, to use this formula with the data set , first you fin...
The mean absolute deviation (MAD) is a direct measure of the dispersion of a random variable about its mean. In this paper, the empirical likelihood (EL) and the adjusted EL methods for the MAD are proposed. The Bayesian empirical likelihood, the Bayesian adjusted empirical likelihood, the ...
absolute deviation (redirected fromMean Absolute Deviation) Acronyms absolute deviation [′ab·sə‚lüt dēv·ē′ā·shən] (ordnance) The shortest distance between the center of the target and the point where a projectile hits or bursts. ...
The mean absolute deviation about the mean is an alternative to the standard deviation for measuring dispersion in a sample or in a population. For stationary, ergodic time series with a finite first moment, an asymptotic expansion for the sample mean absolute deviation is proposed. The expansion...

In short routine experiments involving small samples from a normal distribution, it is often found to be more convenient to use the sample mean absolute deviation (m) rather than the sample standard deviation (S) in forming confidence intervals. Approximate and exact methods for correctly using m...
Mean Deviation (MD)=∑|xi−xˉ|nWhere xi are the individual observations and n is the number of observations. Calculating the absolute deviations:1. |37−40.33|=|−3.33|=3.332. |48−40.33|=|7.67|=7.673. |50−40.33|=|9.67|=9.674. |23−40.33|=|−17.33|=17.335. |47−...
