In [[mathematics]], the term "symmetric function" can mean two different concepts.

Line 17:

{{main|U-statistic}}

In [[statistics]], an ''n''-sample statistic (a function in ''n'' variables) that is obtained by [[bootstrapping (statistics)|bootstrapping]] symmetrization of a ''k''-sample statistic, yielding a symmetric function in ''n'' variables, is called a [[U-statistic]]. Examples include the [[sample mean]] and [[sample variance]].
