Abstract

This study aims to investigate student performance in the Statistics Course, using machine learning, at ACLEDA University of Business, so that students at risk of academic failure can be identified. The study employs a dataset comprised of the academic records of 1,074 students. The records include final exam scores, ongoing assessments (homework and quizzes), and midterm grades. Orange software is a tool used to process data and train models using a number of machine learning algorithms, including K-nearest neighbors, Random Forest, Logistic Regression, Support Vector Machine, and Naïve Bayes. The findings indicate that midterm performance and continuous assessments are powerful predictors of final exam success, and that difficulties on final exams are associated with subpar performance in these domains. Equal-width discretization was used to classify the data in order to control for outliers and examine non-linear relationships. Classification accuracy, precision, recall, F1 score, and AUC were used to assess the model's effectiveness. This study demonstrates how machine learning can give teachers information about how well their students are performing, allowing for more focused interventions and a more encouraging learning environment.
