This talk continues on from my confirmation where an outline of my research and the results for the first two phases of my project were given. In this talk I predominantly present the steps taken to evaluate the survey tool, which is a modified and extended Technology Acceptance Model (TAM). This measurement scale determines the perception of psychology students about the ease of use and usefulness of statistical concepts and their application in psychology using the statistical software, SPSS.
The proposed model was tested for its reliability and structural validity using data collected from a survey of first year psychology students studying statistics during the global pandemic in 2020. To explore the structure of the constructs of students’ attitude, confidence and perception, an Exploratory Factor Analysis (EFA) was conducted on the responses data set. Five latent variables were identified. Utilizing maximum likelihood estimates in Confirmatory Factor Analysis (CFA), and Analysis of Moment Structures (AMOS), the results supported the proposed EFA model. In addition, results of the CFA indicated that the best fitted model had correlations among four of the five constructs. Internal consistency estimates utilizing alpha coefficients, ranged from 0.81 to 0.88 with only one exception of 0.682. The findings provide a valid and reliable assessment of students’ attitudes towards statistics for predicting academic performance. Consequently, this may help as a guide for effective decision-making in the design and development of the statistics subjects for students with a non-mathematical background.
