This research work examines the Implementation of Kruskal-Wallis Test statistic on students’ performances in; Introduction to Computing (COM101), General Physics (GNS 103), Functions and Geometry (MTH112), and Technical English (OTM 112) for the 2015/2016 academic session only. The data analyzed was from the department of computer science, N.D. 1, Reg. 1. A random sample of 24 student scores of all 4 population location(courses) was considered. The data collected was analyzed, using the Nonparametric Alternative: Kruskal-Wallis Test. The results prove that there is a difference in students’ performances across their courses of study. (i.e. In every 4 courses of study, at least two courses must differ in terms of student performances).
