Supplementary Dataset for High-Impact Practice Profiles and Academic Achievement

This dataset contains anonymized supplementary materials supporting the article “Privilege or pathway? Unequal academic returns from high-impact practices in higher education.” It includes robustness checks, methodological validation procedures, and statistical outputs associated with the latent profile analysis and the relationship between High-Impact Practice (HIP) participation and academic achievement among 1,689 final-year undergraduate students. The dataset provides regression diagnostics, bootstrap replications, sensitivity analyses, heteroscedasticity tests, influential case assessments, and cross-validation metrics. These materials ensure transparency, replicability, and methodological rigor, offering researchers additional evidence on the stability and reliability of the study's findings within a stratified Global South higher education context.
