A Statistical Analysis Of The Performance Distance Learning Students And The Full-Time Students At The University Of Lagos

The study compares the performance of distance learning students with full-time students in a traditional face-to-face learning environment. This study is one aspect of a larger research project designed to gain insight into factors that may influence the performance of distance learning students. The data used in the study represent the graduating GPA (Grade Point Average) and CGPA (Cumulative Grade Point Average). The result showed that students of Distance Learning Institute (DLI) performed better in business administration than the mainstream students, while the mainstream accounting students perform better than the DLI accounting students. Results indicated that there was a statistically significant difference in final grades of these groups of students

COMPARATIVE STUDY OF BAYESIAN AND ORDINARY LEAST SQUARES APPROACHES

Frequentist (Classical) and Bayesian are two major approaches to data analysis in statistics, however, the difference is how both see a parameter. Frequentists see a parameter as constant value while the Bayesians see it a random variable. Research work recently has witnessed increase in the application of Bayesian methods to statistical problems and in other fields. For linear regression modelling, frequentists use more often the Ordinary Least Squares (OLS) method despite violation of some assumptions. Bayesian approach can be used when assumptions in linear regression model using OLS are not met. Using two different data sets, an empirical study was performed using both OLS and Bayesian approaches to linear regression modelling. The analysis showed that the resulting linear regression model using OLS does not meet all required assumptions for a good model. The Bayesian approach as an alternative to regression modelling was further established based on results using several criteria such as RMSE, MAPE and MAD. The results showed that linear regression modelling using Bayesian approach is better than Frequentist method using OLS regression modelling
