The relationship between reproducibility standard deviation and mass fraction in food analysis has been studied in compilations of statistics from collaborative trials and from proficiency tests. There was a broad tendency for both categories of stat

In the FAPAS proficiency testing scheme, participants are asked to state whether the analytical method used was accredited or not accredited. It is thus possible to compare the stated accreditation status with performance in the scheme. For this purp

A meta-analysis of statistics from many proficiency tests has demonstrated the wide applicability of a simple model of reproducibility (interlaboratory) standard deviation. The function has already been proposed as a model for uncertainty in an analy
