The test-structure paraphrase is supported; the book's inference is not safe to reuse unchanged. PDF pp. 188/195 confuse non-significance with equivalence and misinterpret alpha. Table 7 has 14 entries under the printed 30% heading one below exact binomial thresholds. Use independent responses, preselected alpha and power; a non-significant result does not establish sameness.
The chapter contrasts casual feedback with blinded discriminatory testing and gives a simplified statistical example.
In a triangle test, assessors receive three coded samples—two alike and one different—and identify the odd sample. Randomized presentation and a sufficient number of independent assessors allow the result to be evaluated against chance.
