Given a probability distribution (density) function fX(x) with random variableMathworldPlanetmath X and x, a mode of fX(x) is a real number α such that:

  1. 1.


  2. 2.

    fX(α)fX(z) for all z.

The mode of fX is the set of all modes of fX (It is also customary to say denote the mode of fX to be elements within the mode of fX). If the mode contains one element, then we say that fX is unimodal. If it has two elements, then fX is called bimodal. When fX has more than two modes, it is called multimodal.
