Quantifying user research

Abstract

User research is a broad term that encompasses many methodologies, such as usability testing, surveys, questionnaires, and site visits, that generate quantifiable outcomes. Usability testing is a central activity in user research and typically generates the metrics of completion rates, task times, errors, satisfaction data, and user interface problems. You can quantify data from small sample sizes and use statistics to draw conclusions. Even open-ended comments and problem descriptions can be categorized and quantified.
