The degree to which numerical data are dispersed or squished around an average value is referred to as dispersion in statistics. It is, in a nutshell, the dispersion of data. A vast amount of data will always be widely dispersed or firmly packed.

WebThe optics convert the angular dispersion into a linear dispersion at the target surface, defined as the change in position on the surface as a function of the wavelength, as shown in Figure G-2. In general, the linear dispersion is given by. ∂λ/∂x = (cos(β)∙10-6) / mDf (3) A measure of statistical dispersion is a nonnegative real number that is zero if all the data are the same and increases as the data become more diverse. Most measures of dispersion have the same units as the quantity being measured. In other words, if the measurements are in metres or seconds, so is the measure of dispersion. Examples of dispersion measures include:
