MeasuringU, United States
The purpose of this course is to provide an introduction to the UX-LITE, a relatively new UX questionnaire that contains just two items focused on the core issues of perceived usefulness and perceived ease-of-use. This introduction will include background on standardized usability measurement, where the UX-LITE came from, the research supporting its use as a measure of UX in research and applied UX work, and how to analyze UX-LITE data. At the end of the course, attendees will know the history of the UX-LITE, how to use it in current work, and where future research is likely to go.
The course starts with coverage of the basic psychometric properties of standardized measurement – reliability, validity, and sensitivity. The next topic is a brief review of the inventory of post-study questionnaires. This will lead into a theoretical discussion of the statistical connections between the UX-LITE, the System Usability Scale, and the Technology Acceptance Model. From here, the tutorial moves to the practical use of the UX-LITE through data analysis/interpretation and numerous quantitative exercises. After completing this course, attendees will have a firm foundation in why and how to use the UX-LITE.
The course will likely be of interest to a wide variety of attendees, but will be especially useful to those user experience practitioners and HCI researchers who need a very concise standardized measure of user experience. Attendees should have access to computers with spreadsheet software to work through the quantitative exercises.
