Basic Question: Are two products different from one another?
Basic Setup
25-50 panelists
Screened for acuity (keenness or sharpness of perception, i.e. can they smell and taste well?)
Given triangle, duo-trio or paired comparison tests
Analysis is done using tables which compare results to chance – this analysis ensures that the difference was real and not because people chose the correct sample by luck/chance
Advantage
Quick and simple
Limitations
Limited results – only yes they are different or no they are not
