Overview

symmetric distribution


Show Summary Details

Quick Reference

The random variable X has a symmetric distribution if and only if there is a number c such that

P(X < ck)=P(X > c+k),    for all k.

In this case the distribution is symmetric about c. If X has a symmetric distribution and expectation μ, then c=μ. A distribution that is not symmetric is called an asymmetric distribution.
