Which practice most improves data accuracy in field data collection?

• A. Rely on memory without documentation
• B. Collect data once and never verify
• C. Verify data with records when possible to ensure accuracy
• D. Use only digital data and exclude paper records

Answer: (C)

Verifying data against existing records whenever possible is the most reliable way to improve field data accuracy. Records provide an independent reference that helps confirm what was observed or reported, catching transcription mistakes, misread values, or missing fields. By cross-checking collected information with source documents, logs, inventories, or databases, you can correct discrepancies on the spot and maintain an accurate, auditable trail. This habit reduces the chance that data used for decisions is wrong, which is essential for reliable monitoring and reporting.

Relying on memory without documentation invites recall errors and gaps in context. Collecting data once and never verifying allows mistakes to go unnoticed. Relying exclusively on digital data and excluding paper records isn’t inherently more accurate and can miss information that hasn’t been digitized or can be lost if the system fails.
