Which data quality attribute means data is free from errors and representative of real-world situations?

• A. Timeliness
• B. Accuracy
• C. Validity
• D. Completeness

Answer: (B)

Accuracy is the data quality attribute that means data values are correct and true to reality. It ensures data is free from errors and faithfully reflects real-world measurements or facts. For example, a recorded sales amount should match the actual transaction, and a customer’s address should correspond to where they live. When data is accurate, analyses and decisions based on it align with what’s really happening. Timeliness discusses how current the data is, completeness covers whether all required data is present, and validity checks that data follows defined formats or rules.
