The degree of scatter shown by observations. It is usually measured as an average deviation about some central value (e.g. mean deviation, standard deviation) or by an order statistic (e.g. quartile deviation, range) but may also be a mean of deviations of values among themselves (e.g. Gini’s mean difference and also standard deviation).
