User-based statistical evaluation
From EuroVR Knowledge Base
Description
User-based statistical evaluation involves conducting small empirical studies to determine the effect of specific design factors on user task performance. These studies typically target a specific part (e.g. a particular feature) of the user interface instead of examining the usability of the whole user interface. Users are required to carry out tasks which involve the use of the interface component of interest. Performance measures such as time taken to perform the task(s) and task accuracy may be recorded. Usability ratings may also be of interest. An iterative design and user-based statistical evaluation process can help to improve interface components prior to conducting application-specific formative evaluations (Hix et al., 2004).
