Dispersion, in physics, is the result of light refracting in a material. The different wavelengths of light will "bend" at different angles depending on their wavelength. As the refracted light approaches a critical angle at which all the light will be reflected instead of passing through the material the maximum amount bend that the light can achieve occurs. At this point the human eye can begin to perceive the different bends that each color experiences in the material.
Dispersion, in statistics, is the extent to which values of a variable differ from a fixed value such as the mean.

What is the difference between Dispersion and Skewness?
distinguish between dispersion and skewness
What is dispersion and various measures of dispersion?
Dispersion is the act of spreading people or things (like seeds) out over a large area. Measures of dispersion tell us the degree of variation of values in a sample or population.
What is natural dispersion?
Dense smoke from a forest fire - would disperse in the atmosphere. This would be an example of natural dispersion
What is difference between absolute measure of dispersion and relative measures of dispersion?
The Absolute Measure of dispersion is basically the measure of variation from the mean such as standard deviation. On the other hand the relative measure of dispersion is basically the position of a certain variable with reference to or as compared with the other variables. Such as the percentiles or the z-score.
