Abstract

Empirical measurement, monitoring, analysis, and reporting of learning outcomes in higher institutions of developing countries may lead to sustainable education in the region. In this data article, data about the academic performances of undergraduates that studied engineering programs at Covenant University, Nigeria are presented and analyzed. A total population sample of 1841 undergraduates that studied Chemical Engineering (CHE), Civil Engineering (CVE), Computer Engineering (CEN), Electrical and Electronics Engineering (EEE), Information and Communication Engineering (ICE), Mechanical Engineering (MEE), and Petroleum Engineering (PET) within the year range of 2002–2014 are randomly selected. For the five-year study period of engineering program, Grade Point Average (GPA) and its cumulative value of each of the sample were obtained from the Department of Student Records and Academic Affairs. In order to encourage evidence-based research in learning analytics, detailed datasets are made publicly available in a Microsoft Excel spreadsheet file attached to this article. Descriptive statistics and frequency distributions of the academic performance data are presented in tables and graphs for easy data interpretations. In addition, one-way Analysis of Variance (ANOVA) and multiple comparison post-hoc tests are performed to determine whether the variations in the academic performances are significant across the seven engineering programs. The data provided in this article will assist the global educational research community and regional policy makers to understand and optimize the learning environment towards the realization of smart campuses and sustainable education.

1. Data

The emerging field of learning analytics may be exploited to improve learning outcomes of engineering undergraduates in higher institutions of developing countries towards attaining sustainable education in the region [19], [20], [21]. Useful information about the academic performances of undergraduates that studied engineering programs at Covenant University, Nigeria are presented and analyzed in this data article. Covenant University is located in Ota, Ogun State in Nigeria (Latitude 6.6718o N, Longitude 3.1581o E). It is a private Christian university affiliated with Living Faith Church Worldwide and a member of the Association of Commonwealth Universities (ACU), Association of African Universities (AAU), and National Universities Commission (NUC).

A total population sample of 1841 undergraduates that studied Chemical Engineering (CHE), Civil Engineering (CVE), Computer Engineering (CEN), Electrical and Electronics Engineering (EEE), Information and Communication Engineering (ICE), Mechanical Engineering (MEE), and Petroleum Engineering (PET) within the year range of 2002–2014 are randomly selected. The earliest year of entry and the latest year of graduation are 2002 and 2014 respectively. Having excluded undergraduates with incomplete academic records, 198, 152, 374, 407, 349, 166, 195 undergraduates were pooled from CHE, CVE, CEN, EEE, ICE, MEE, and PET respectively. The descriptive statistics of the academic performances of undergraduates in each of the seven engineering programs at Covenant University are presented in Table 1, Table 2, Table 3, Table 4, Table 5, Table 6, Table 7.

Fig. 1 shows the variations in the GPA data of all the engineering undergraduates under investigation. Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8 illustrate the differences and trends in the GPA data of undergraduates in CHE, CVE, CEN, EEE, ICE, MEE, and PET respectively. The frequency distributions of the GPA data of undergraduates in CHE, CVE, CEN, EEE, ICE, MEE, and PET are shown in Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15 respectively.

2. Experimental design, materials and methods

For the five-year study period of engineering program, Grade Point Average (GPA) and its cumulative value of each of the sample were obtained from the Department of Student Records and Academic Affairs. In order to encourage evidence-based research in learning analytics, detailed datasets are made publicly available in a Microsoft Excel spreadsheet file attached to this article. Descriptive statistics and frequency distributions of the academic performance data are presented in tables and graphs for easy data interpretations. In addition, one-way Analysis of Variance (ANOVA) and multiple comparison post-hoc tests are performed to determine whether the variations in the academic performances are significant across the seven engineering programs. Data showing whether there are significant differences in the GPA data of the engineering undergraduates throughout their five-year study period are presented in Table 8, Table 9, Table 10, Table 11, Table 12, Table 13. The boxplots of the GPA distribution by program are shown in Fig. 19, Fig. 20, Fig. 21, Fig. 22, Fig. 23, Fig. 24. The results of the post-hoc test conducted to understand the extent of significant variations in cumulative GPA across engineering Programs at Covenant University are presented in Table 14. Multiple comparison plots of Cumulative GPA data in Fig. 25, Fig. 26, Fig. 27, Fig. 28, Fig. 29, Fig. 30, Fig. 31 reveal groups (i.e. other engineering programs at Covenant University) whose statistical means are significantly different.
