Web Survey Bibliography
Web questionnaires are the most frequently used type of data collection method in Internet-based research. With Askito (http://askito.deusto.es) we propose a tool to create Web questionnaires that fulfills the criteria of being usable, non-commercial, AJAX-based, and open source. Askito currently offers seven basic question types, among them several ones that are hard to find in any other online questionnaire tool: Sorting of terms via drag and drop, Semantic Choice displays popups with verbal descriptions on a scale, and with Assignment items can be dragged and dropped to fields in categorization tasks.
