The KODAQS Toolbox: An Open Educational Resource for Ensuring Data Quality

Valid conclusions can only be drawn when data meets rigorous quality standards, and when researchers are equipped with the appropriate tools and expertise to assess them. Ensuring data quality has become particularly important within the social sciences due to increasingly complex research settings, a declining willingness to participate in surveys, and the growing reliance on automated and scalable evaluation of available data. To this end, we present the KODAQS Data Quality Toolbox, developed as part of the BMBF/EU-funded Competence Center for Data Quality in the Social Sciences (KODAQS). The KODAQS Toolbox provides tools and tutorials on conducting key data quality analysis to help social scientists evaluate and improve the quality of their research data. The Toolbox covers three main data types: 1) survey data, 2) digital behavioral data, and 3) survey data linked with data from other sources, recognizing that challenges for data quality differ greatly for these data types. At its core, the KODAQS Toolbox employs containerized environments to render literate programming-based contributions from open repositories into HTML pages as well as downloadable Jupyter Notebooks, Quarto files, and PDFs, ensuring the reproducibility of its materials. As an educational platform, the Toolbox lowers entry barriers for learners by providing reusable code, embedded video tutorials, sample datasets, self-assessments, and downloadable source files – all designed to support hands-on learning. In addition, it incorporates Binder-based interactive execution environments that allow users to run the learning materials directly in their browser without requiring complex setup. The underlying open-source framework of the Toolbox allows straightforward integration of new tools and tutorials, making it an ideal platform for contributors to share their content. Beyond its immediate use, the Toolbox serves as a transferable model, demonstrating how modular, open, and reproducible content can be effectively aggregated to support a wide range of research domains.Acknowledgements This work is developed as part of the BMBF/EU-funded Competence Center for Data Quality in the Social Sciences (KODAQS).
