Review & Clean Your Data
Perform Data Quality Control
After participants have entered their information into your registry, review the data to identify and correct entry errors. Identify any problems that may affect the data collection process, such as issues with converting addresses to the standard U.S. Postal Service format or other glitches that prevent participants from completing certain fields. If participants commonly skim over specific questions, assess whether the question can be rephrased. Consider whether the question asks for information that participants are uncomfortable providing.
Examples of common data entry errors:
- Incomplete fields
- Incorrect data
- Missing data
- Duplicate submissions
Use the RaDaR Tool: Data Quality Control Checklist to help you access the quality of the data you’ve collected for your registry.
