Synopsis

A preferred measure of spread is the standard deviation.

Measure of spread are descriptive statistics or summary statistics and fall under the data analysis step in the Statistical investigation process. Generally the first descriptive or summary statistics looked at are measures of center but alone these can be misleading. A useful numerical description of a distribution requires both a measure of center and a measure of spread.
