The sequential selection of judges for organoleptic testing

Both the theory of sequential analysis developed by Wald and that developed by Rao may be applied to binomial distributions and may be used to select judges for taste testing experiments. The duo-trio or triangle test may both be used as the fundamental test in either sequential process. Wald has applied his sequential analysis to binomial distributions and it was only necessary to associate duo trio and triangle trials with his examples on industrial sampling inspection. This was done by associating incorrect tasting decisions with defectives in industrial sampling. It has been noted Ghat choice of α and β, the risks of type I and type II errors, may depend on the availability of potential judges and on the time and material available to the experimenter.
