Along with the variability dispersion of a dataset central tendency is a branch of descriptive statistics.
This gives the mean absolute deviation MAD about a for ungrouped data ie MAD a large frac sumn_i1 x_i an In case the measure of central tendency is mean the above equation can be rewritten as. It is also called raw data. It is the numerical method that provides the summary of the datasetIt focuses on the central distribution of data through a single value. MADbar x large frac sumn_i1 x_i bar xn Where bar x Mean.
