In complex surveys aimed at measuring the satisfaction level of final users of a given product or service, several items are generally investigated. Also, respondents often belong to different categories since they are stratified according to relevant features, such as geographic location or gender. In such situations, the comparison among the distributions of ratings given to a selection of items by interviewees or to a single item by different groups of interviewees can provide a meaningful summary of observed data. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
