Quizplus · Accepted Answer

Duo-trio and Triangle tests are specific methodologies used in sensory evaluation to determine if a perceivable difference exists between samples. The Duo-trio test involves a reference sample followed by two other samples, one of which is identical to the reference, and the participant must identify the match. The Triangle test presents three samples, with two being identical and one different, and the participant must identify the odd one out. Both are designed to assess if a noticeable difference exists, not to determine preference or describe differences.
