A Comparison of Students’ Performance: An Application of Hotelling’s
Journal Title: Scholars Journal of Physics, Mathematics and Statistics - Year 2016, Vol 3, Issue 4
Abstract
This paper examined the equality of the performance of two sets of students: those who graduated in 2012/2013 and 2013/2014 academic sessions from the Department of Statistics, Abia State Polytechnic, Aba, Nigeria, based on their scores in the same eight courses which both sets offered during their second semester HND II. Hotelling’s was applied to the data. The analysis and tests showed there is a significant difference in performance between the two sets. A Roy-Bose simultaneous confidence interval was used to identify the mean vectors that contributed to the rejection of the null hypothesis. The result showed in general that students who graduated in 2012/2013 academic session performed better than those who graduated in 2013/2014 academic session.
