The standard deviation of a random variable divided by the mean.

Its dimensionless form makes it convenient for summarization.

The United States Bureau of Census alternatively refers to the coefficient of variation as the ratio of the standard error to the value being estimated, usually expressed in terms of a percentage. Also known as the relative standard deviation. (United States Bureau of Census, Glossary of Selected Abbreviations and Acronyms - refer http://www.census.gov/dmd/www/glossary.html)>.
