We have a software package used by our sensory lab, and one basic test that is done is a 'Triangle Test', where tasters are presented 3 samples, A B and C, of two products, 1 and 2.

For taster #1, A and B might be the same (Product 2), while C is different (Product 1); for taster #2 it might be A and C (Product 1), with B being different (Product 2). Etc. Etc. The tasters select which of A, B, or C they think is the odd man out.

The goal is to determine if there is a significant difference between Product 1 and 2.

The software package appears to use a Pairwise t-test to evaluate the results. Is this the correct way to do this in JMP?

The data for each taster would seem to me to be simply a 0 or 1, as in 'they either did or did not detect a difference'.

Please advise how I might analyze these results in jmp (I have 6.0.3) and how the data table should be built. Thank you, D. Lewis
