During January 2025, Halley1116 developed a comprehensive health insurance data analysis notebook for the 2025_DA_study repository, focusing on end-to-end data loading, exploratory data analysis, and preprocessing. Using Python, Pandas, and Jupyter Notebook, Halley1116 implemented robust missing-value handling by filling medical_history and family_medical_history fields with 'No History', ensuring data quality and analytical consistency. The work also included converting categorical features to dummy variables to support further analysis. Additionally, Halley1116 consolidated project documentation, standardized naming conventions, and removed obsolete files, which improved onboarding and reproducibility. The contributions demonstrated thoroughness in both technical execution and project organization.
