Quizplus · Accepted Answer

Standard deviation is the most commonly used measure of dispersion because it takes into account every data point and provides a more precise measure of how spread out the data is. Range and mean deviation are less precise measures of dispersion and variance is less commonly used because it is in squared units which can be more difficult to interpret.
