Comparing Two Examination Results using Means of Sample Means and Control Charts

Abstract

Some examination candidates submit their scripts first, sometimes, for recognition as being brilliant, and some do for not knowing what to write. However, some equally submit last because they want to dot i’s and cross t’s. The objective of this research is to compare the results of both the earliest and latest submissions with the aim of finding out whether or not there is a significant difference between the two. The examination results of students of the Departments of Accounting, Business Administration and Industrial Relations and Personnel Management of the Faculty of Business Administration and the Department of Mathematics, Faculty of Science,  University of Lagos were  compared using means of sample means and two statistical quality control charts. The results showed that, generally, the early submissions seemed to be an indication of being more brilliant than the last submissions in the Faculty of Business Administration. In the Mathematics Department, however, the last to submit appeared to be more brilliant.
