Evaluation of questionnaires by means of formal concept analysis

The paper presents a method of evaluation of questionnaires. The method is supported by formal concept analysis. The role of formal concept analysis consists in providing an expert with a structured view on the data collected from the questionnaires. The method resulted from experiments with IPAQ (International Physical Activity Questionnaire). The structured view on data provided by the method suggests to the ex- pert various hypotheses which can later be tested using statistical meth- ods. However, the structured view on data itself proved to be sufficiently informative quite often. The paper presents experiments with evaluation of IPAQ.
