measure of spread
A measure of the extent to which the values of a variable, in either a sample or a population, are spread out. The most commonly used measures of spread are variance, standard deviation, mean deviation, median absolute deviation, range, interquartile range, and semi-interquartile range. Of these only the variance is not measured in the same units as the observations.
