The effect of blended learning implementation on the academic achievement of Binus University students in the business statistics course

This study investigates the effect of blended learning implementation on the academic achievement of undergraduate students enrolled in the Business Statistics course at Bina Nusantara University (BINUS), Indonesia. Blended learning, a pedagogical approach that systematically integrates conventional face-to-face classroom instruction with structured online digital activities, has gained considerable prominence in higher education, particularly in the context of the educational disruptions caused by the COVID-19 pandemic. Employing a descriptive quantitative research design with a cross-sectional time horizon, the study collected academic performance data from 50 students through structured questionnaires and interviews. Statistical analyses—including the Kolmogorov–Smirnov normality test and the Kruskal-Wallis non-parametric test—were applied to examine the distributional characteristics of and significant differences between the online and offline components of blended learning. Results indicate a statistically significant difference between the two modalities (χ² = 74.257 > χ²table = 3.84; p = 0.000
