Data validation is important for ensuring regular monitoring of your data and assuring all stakeholders that your data is of a high quality that reliably meets research integrity standards — and also a crucial aspect of Yale's Research Data and Materials Policy, which states "The University deems appropriate stewardship of research data as fundamental to both high-quality research and academic integrity and therefore seeks to attain the highest standards in the generation, management, retention, preservation, curation, and sharing of research data."
Basic methods to ensure data quality — all researchers should follow these practices:
Advanced methods to ensure data quality — the following methods may be useful in more computationally-focused research:
Data validation and quality assurance is often discipline-specific, and expectations and standards may vary. To learn more about data validation and data quality assurance, consider the information from the following U.S. government entities producing large amounts of public data:
