Cronbach’s Alpha was used to test the reliability of the questionnaire in this study,
and the coefficient reliability indicates a value of 0.868 for independent
variables and 0.726 for dependent variable which values are higher
than 0.7 (Sekaran & Bourgie, 2010). Thus, it can be concluded that the
instrument measuring the variables in this study is valid and reliable.
The data entries were assessed twice by the researcher and an assistant
researcher. The two sets of data were compared and adjusted where
differences were found in the data derived from the first and second
assessments. The final data were analysed using the statistical software
programme, SPSS version 21. The equation of the multiple regression
model used is shown below:
