Understanding data quality
Why Data Accuracy and Validation Matter
Data quality affects research, business reporting, software systems, statistical analysis and machine learning. A dataset can contain useful information while still having problems that affect its reliability.
Accuracy
Accuracy describes how closely recorded values represent the real-world values or facts they are intended to describe.
Completeness
Completeness concerns whether the required information is present and whether important values are missing.
Consistency
Consistency concerns whether information follows compatible formats, definitions and rules across records and systems.
Integrity
Data integrity involves preserving information correctly and ensuring that relationships and constraints remain valid.
