The effect of Z-Score on Year Grade Point Average (YGPA) and Final Grade Point Average (FGPA) in Faculty of Engineering, General Sir John Kotelawala Defence University (KDU)

A collection of 182 Intake 35 day scholar undergraduates who had followed the Local GCE Advanced Level examination from the Faculty of Engineering, General Sir John Kotelawala Defence University (KDU), was selected. Data was collected from the several departments and units of KDU. The Grade Point Average (GPA) was considered the scale of a student’s academic performance in the study. A descriptive analysis was performed to differentiate the configuration of the data and the relationship between the Year Grade Point Average (YGPA), and Final Grade Point Average (FGPA) variables with the Z-Score. Spearman and Kendall rank correlation tests were performed in the analysis. The results indicated that the Z-score has a comparatively strong positive relationship with student’s performance at the university in their first year and the class selection.
