PROFILE
Sy Chen
Over four months, Pei-Chun Chen developed a comprehensive, chapter-based statistics education resource library for the HWTeng-Teaching/202509-Statistics repository. Chen focused on building structured Markdown documentation that consolidates problem statements, step-by-step solutions, and analyses across chapters 2 through 12. Using Python, Pandas, and Matplotlib, Chen created reproducible data visualizations and statistical analyses, while establishing standardized naming conventions and modular scaffolding to ensure maintainability and scalability. The work emphasized clear technical writing, consistent documentation practices, and cross-chapter navigation, resulting in a curriculum-ready resource that streamlines lesson planning, accelerates learner onboarding, and supports ongoing content expansion without introducing defects.
