Statistical Analysis for Assessing Sample/Practice Exams in Undergraduate Engineering Education

Abstract

The inclusion of practice exams in undergraduate engineering courses was assessed utilising survey results and the analysis of variance (ANOVA) tools. Data collected was from the survey completed by students and students' grades spanning over two semesters, one with implementing practice exams and the other without. Results based on survey indicated that there was a very strong consensus among students about the usefulness and validity of such course improvement. Furthermore, the statistical analysis results using the ANOVA and the independent samples t-test tools also showed a significant increase, on the 0.05 significance level (or 95% confidence level), in students' academic procurement when utilising the practice exams technique. Therefore, it is recommended that sample exams be implemented in undergraduate engineering education to enhance students' earnings and their learning experience.
