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
tesing 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 Î± and Î², the riskso! type
I and type II errors, may depend on the availability of
potential judges and on the time and material available to
