Hence, with the purpose of reducing effort and When designing a usability evaluation, key decisions must increasing return of investment, the last decade of usability be made regarding methods and techniques for data research has investigated extensively into questions such as collection and analysis. Although there is a strong body of which experimental methods to apply [3], how many research within human-computer interaction regarding the evaluators to involve in expert- and user-based studies [2], appropriate choices of data collection methods and how many test subjects to use for user-based studies [8, 17, techniques, much less research has been conducted 19], and in which settings to conduct the evaluations [4, 5, examining and comparing methods and techniques for 9]. Providing tools for conducting usability evaluations ‘at a analyzing the collected data. This paper presents a data discount’ [9, 10, 11, 12], this research has greatly improved analysis technique which allows usability evaluations to be software designers’ and researchers’ ability to select the c
