Weighted Means Statistics in Interlaboratory Studies

Published

Author(s)

Andrew L. Rukhin

Abstract

The usefulness of weighted means statistics as a consensus mean estimator in collaborative studies is discussed. A random effects model designed to combine information from several sourcesis employed to justify their appeal to metrologists. Some methods of estimating the uncertainties and of constructing confidence intervals are reviewed.
