{{Complex}} In the comparison of [[statistics|statistical procedures]], '''efficiency''' is a measure of an [[estimator]]'s quality. This would be about the estimator of an [[experimental design]],{{sfn|Everitt|2002|p=128}} or of a [[hypothesis testing]] procedure.<ref>{{SpringerEOM | title= Efficiency of a statistical procedure| id=E/e035080 | last=Nikulin | first=M.S.}}</ref> Basically, a more efficient estimator, experiment, or test needs fewer observations than a less efficient one to get a given performance. ==References== {{reflist}} {{statistics}} {{Math-stub}} [[Category:Statistics]]
