 Abstract:

Self-efficacy determines students’ capabilities in designing their performance and personal well – being. How their feelings and motivation shape the success whenever tasks are given to them. This study aimed at assessing the psychometric properties of statistical self-efficacy among 241 postgraduate students that been selected using purposive sampling. Survey research design applied and respondents were given a set of the questionnaire of Statistical Self-Efficacy (SSE) instrument which originally has 22 items. The data was analyzed using Rasch Model which produced a good item and person reliability. Likewise, the item fit, unidimensionality of the instrument were tested to identify the psychometric properties of SSE were fulfilled. The data from Rasch analysis had shown that SSE instrument had achieved the central assumptions such as item fit and unidimensionality. The analysis also covered item polarity, Wright Map, reliability and separation index. Although, past researchers have studied self-efficacy, yet some limitations including the psychometric properties have been overcome in this research.  Thus, the Rasch Model analysis provides empirical evidence for SSE for future studies, particularly in the psychometrical aspect.
