Understanding Measures of Dispersion by charadam is a document available to read on EtoBox.
This document discusses various measures of dispersion used in statistics to quantify how spread out or varied data values are from the mean or median. It introduces the range, mean absolute deviation (MAD), variance, standard deviation, and interquartile range. The range is simple to calculate but affected by outliers. MAD is more robust than range but not as smooth as variance. Variance squares distances so it is smoother than MAD but more affected by outliers. Standard deviation takes the square root of
