Round robin test
Encyclopedia
In experimental methodology, a round robin test is an interlaboratory test (measurement, analysis, or experiment
) performed independently several times. This can involve multiple independent scientists performing the test with the use of the same method in different equipment, or a variety of methods and equipment. In reality it is often a combination of the two, for example if a sample is analysed, or one (or more) of its properties is measured by different laboratories using different methods, or even just by different units of equipment of identical construction.
A round robin program is a Measurement Systems Analysis
technique which uses Analysis of Variance (ANOVA) random effects model to assess a measurement system.
Experiment
An experiment is a methodical procedure carried out with the goal of verifying, falsifying, or establishing the validity of a hypothesis. Experiments vary greatly in their goal and scale, but always rely on repeatable procedure and logical analysis of the results...

Purpose
There are different reasons for performing a round robin test:- Determine the ReproducibilityReproducibilityReproducibility is the ability of an experiment or study to be accurately reproduced, or replicated, by someone else working independently...
of a test methodTest methodA test method is a definitive procedure that produces a test result.A test can be considered as technical operation that consists of determination of one or more characteristics of a given product, process or service according to a specified procedure. Often a test is part of an experiment.The test...
or process - Verification of a new method of analysis: If a new method of analysis has been developed, a round robin test involving proven methods would verify whether the new method produces results that agree with the established method
