Bradley, 1963) is a sensory difference test that provides a useful application of the binomial model. In its simplest form, the triangle procedure is as follows. To each of n panelists, three test samples are presented in a randomized order. Two of the samples are known to be identical; the third is different. The panelist is then supposed to select the odd sample, perhaps on the basis of a specified sensory attribute. If the panelists are homogeneous trained judges, the experiment can be viewed as n independent repeated Bernoulli trials, where a success corresponds to a correct identification of the odd sample.

Focus on any particular spot in the table, such as the third digit in the second row. Knowing some or even all of the digits in the table, except for the one you are considering, does not change the probability it will be a 0, or a 1, . , or a 9. This probability remains a 1/10. 3, test the equal likelihood property. 4 Bayes Estimators for the Probability of Success 33 23. Devore (1991) gives an example from the paper “Linkage Studies of the Tomato” (Tran. , 1931, pp 1-19) on phenotypes from a dihybrid cross of tall, cut-leaf tomatoes with dwarf, potato-leaf tomatoes.
