Dispersion (redirected from Dispersion (radiation))

Dispersion

A term used in statistics that refers to the location of a set of values releative to a mean or average level.

Notes:

In finance, dispersion is used to measure the volatility of different types of investment strategies. Returns that have wide dispersions are generally seen as more risky because they have a higher probability of closing dramatically lower than the mean. In practice, standard deviation is the tool that is generally used to measure the dispersion of returns.
