DISPERSION MEASURES In Statistics Are the measurements of mean, variance, fashion, standard deviation of a statistical analysis of a group of data. They can be absolute, as is normally the case when expressed with quantified data for each state or in relative terms, referring to the amount of distance from fashion, or unit modules of deviation ( Xm, Xm sigma, Xm 2 sigma , Xm-sigma , Xm-2sigma, etc.) being Xm the point of the abscissa with the most frequent and highest value of the bell.
