Which metrics help monitor address data quality?

• A. Validation rate, deduplication rate, geo-coding success rate, percent with missing fields, postal-code validity, and time-to-validation
• B. User login count and page views
• C. Memory usage only
• D. Network latency only

Answer: (A)

Monitoring address data quality relies on metrics that reflect accuracy, completeness, and timeliness. Validation rate shows how many addresses pass the validation checks, indicating overall correctness. Deduplication rate reveals how effectively duplicates are identified and removed, which improves uniqueness and reliability. Geo-coding success rate measures how often an address can be mapped to geographical coordinates, signaling practical usability for mapping and routing. Percent with missing fields highlights gaps in data that can hinder downstream processes. Postal-code validity checks ensure codes are correct and standardized, reducing delivery or routing errors. Time-to-validation indicates how quickly addresses are validated, reflecting process efficiency. Together, these metrics give a clear view of the quality of address data. Other options focus on user activity or system performance and do not directly assess address data quality.
