Based on the total population of accounting student groups, the appropriate sample size was statistically
estimated using Yamane’s (1967) formula that yielded a minimum sample size of 300 for the undergraduates and
74 for the graduates. In order to collect data of high quality that reflects the students’ opinion, a survey was
conducted in August, 2014, which yielded a usable 516 and 78 questionnaire for the undergraduate and graduate
groups respectively.
