Abstract:
|
Check-All-That-Apply (CATA) experiments are becoming more and more popular for products characterization and development. CATA task consists of asking the respondents to check off the different attributes that apply to each one of the evaluated products. One of the main objectives of this task is to highlight similarities and differences among the products. CATATIS is a strategy of analysing CATA data that makes it possible to compute an average group configuration of the products taking into account the agreement between the subjects (Llobell et al., 2019). The difference between subjects in product perception is an important topic. While these differences can be highlighted through a clustering approach of the subjects (Llobell et al., 2019), the problem of assessing differences in perception between predefined groups of subjects has not been sufficiently investigated. For example, ‘are the products differently perceived by men and women?’ To address this issue, we propose a permutation test based on the agreement between the group average configurations associated with the group of subjects.
