Statistical modeling and analysis of interlaboratory comparisons pose several fundamental questions about determination of the consensus value and its associated uncertainty. An appropriate choice of statistical model can be difficult especially when measurements are made across a range of values of a physical characteristic, i.e. the reference value is a curve or a multivariate vector. Under.

Proficiency Testing (PT) Schemes and QA systems. Participation to proficiency tests (laboratory evaluating interlaboratory tests) is considered mandatory for laboratories accredited according to ISO/IEC and EN Checking analyses results with those of other laboratories is an important third line quality control element. Dec 10,  · Interlaboratory comparisons are typically used for one of three main purposes, to assess the random variation in measurement results across a population of laboratories, to determine the systematic differences in results among a fixed set of laboratories, or to determine the value of a physical property of an artifact or a population of autohelp.club: William F.
