Abstract

The National Institute of Standards and Technology (NIST) seaweed Standard Reference Material (SRM4359) was developed through an intercomparison of 24 experienced laboratories. Several statistical techniques were evaluated for establishing reference values from careful evaluation of the laboratories reported values including mean, midmean, median, Type B On Bias (BOB), Graybill-Deal, Mandel-Paule, Vangel-Rukhin, Cox and Maximum likelihood. After reviewing the results from all these techniques, the median was chosen as the most robust way to calculate the reference values. The uncertainties for the median values were estimated using bootstrap analysis.
