One measure that does so is the discrete entropy. The sample standard deviation is denoted by the letter s. In other projects Wikimedia Commons. A mean-preserving spread MPS is a change from one probability distribution A to another probability distribution B, where B is formed by spreading out one or more portions of A's probability density function while leaving the mean the expected value unchanged.

Formulas de Medidas de Tendencia Central y Medidas de Dispersión. Formulas. In statistics, dispersion is the extent to which a distribution is stretched or squeezed. Common examples of measures of statistical dispersion are the variance.
Find the deviations from the mean.
Dispersion. For categorical variablesit is less common to measure dispersion by a single number; see qualitative variation. A system of a large number of particles is characterized by the mean values of a relatively few number of macroscopic quantities such as temperature, energy, and density.

In other words, if the measurements are in metres or seconds, so is the measure of dispersion. In other words, they have no units even if the variable itself has units.
