Presented at the 2013 Pangborn Symposium in Rio de Janeiro, Brazil.
Check all that apply (CATA) lists are commonly used in both survey research and sensory science. A related technique, referred to as applicability scoring, requires respondents to respond explicitly to each item of interest -applicability scoring is popular in the survey literature as it avoids several of the limitations of CATA scoring. In this talk, we first review the backgrounds of CATA and applicability scoring, then discuss recent developments that allow for scale estimation from applicability data. We then show how this scale estimation provides a sensitive method for quantifying product differences on a range of attributes that might not be conveniently expressed in a rating or 2-Alternative Forced Choice format.
