Abstract
The purpose of this course is to describe the development and practical use of the UX-Lite, a two-item questionnaire that assesses perceived ease-of-use and perceived usefulness. The course starts with a general background on the concept of usability and how to develop standardized questionnaires. The focus then shifts to the UX-Lite, covering the history of its development and evolution from earlier questionnaires and the findings that support its use as a practical tool for UX research and applied UX work. The second half of the course switches to exercises demonstrating how to analyze and interpret UX-Lite data. At the end of the course, attendees will know how standardized UX questionnaires are developed and assessed, the history of the UX-LITE and its place in the catalog of standardized UX questionnaires, and how to use it in their current work.
Benefits for attendees
Attendees will know how standardized UX questionnaires are developed and assessed, the history of the UX-LITE and its place in the catalog of standardized UX questionnaires, and how to use it in current work.
Course Content
Goals and objectives
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 to a theoretical discussion of the statistical connections between the UX-LITE, the System Usability Scale, and the Technology Acceptance Model. From here, the course 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.
