The results will be analyzed by categorical data using absolute and relative as well as continuous data using average, median, standard deviation, 25 and 75 

In statistics, the median absolute deviation (MAD) is a robust measure of the variability of a univariate sample of quantitative data. It can also refer to the

Reference. MAD is the median absolute deviation from the median.Your formula from class is for the mean absolute deviation from the median.The simple median value is 12, which when multiplied by the default constant of 1.4826 for asymptotically normal consistency gives the reported value of 17.7912. The median absolute deviation of a set of quantitative observations is a measure of dispersion. It corresponds to the mean of the absolute values of deviation of each observation relative to the Median absolute deviation. Robust measure of the variability of a univariate sample of quantitative data. Wikipedia.

2009-01-01 · The Median Absolute Deviation (MAD) is a simple way to quantify variation. Half the values are closer to the median than the MAD, and half are further away. GraphPad Prism does not (yet) compute the MAD. The best way to understand the MAD is to understand how it is calculated. First, compute the median of all the values.

The mean absolute deviation is calculated using a combi y = mad(X,flag,vecdim) returns the mean or median absolute deviation over the dimensions specified in the vector vecdim.For example, if X is a 2-by-3-by-4 array, then mad(X,0,[1 2]) returns a 1-by-1-by-4 array. Each element of the output array is the mean absolute deviation of … Median Absolute Deviation Description. Compute the median absolute deviation, i.e., the (lo-/hi-) median of the absolute deviations from the median, and (by default) adjust by a factor for asymptotically normal consistency.
