Resumé

Statistical tools to assess the agreement of respondents in a Check-All-That-Apply (CATA) experiment are discussed. An overall index of agreement is introduced and a hypothesis test to assess the significance of this index is outlined. A similar investigation at the level of each attribute is undertaken. The permutation test proposed in this latter situation can be compared to Cochran’s test. We also propose to cluster the respondents while setting aside those respondents that are deemed to be atypical. This strategy of clustering stands a refinement of the cluster analysis called CLUSCATA that was introduced in a previous paper. The various strategies of analysis are illustrated by means of real case studies.
