The Use of Tau Statistic Reliability Measure for Academic Performance: A Lesson for University Students

Abstract:

The poor performance of tertiary graduates in Nigeria has been the subject of speculation for stakeholders in the education sector every year, mainly because of its target of becoming one of the world's top 20 economies this year. Performance is the ability of a student to complete a task. The task completion results could be positive or negative. If it is positive, it indicates that the student performs brilliantly or excellently, but on the other hand, if it is negative, it indicates woeful performance. Student performance is an outcome of a rigorous evaluation through examination or other assessment methods. Performance criteria start from day one on campus, and it extends and accumulates to the end of the student's study. The study uses the academic records of students from seven Engineering department from the School of Engineering, Covenant University, Nigeria. This study aims at examining the relationship between the first year and final year results and the reliability between first year results and final year results from seven Engineering departments. The result of the Pearson correlation coefficient shows there is a strong positive correlation between the students the first year and final year result and it also shows there is a significant linear relationship between students first and final year result from the seven departments. This work will serve as a valuable source of advice to stakeholders in the education sector, inside and outside the university system, to enhance the academic performance of students in the University system.
