Which practice reduces data-entry errors?

• A. Use validation checks and double-check entries
• B. Guessing values
• C. Enter quickly and correct later
• D. Disable input validation

Answer: (A)

Reducing data-entry errors hinges on catching mistakes at the moment data is entered. Validation checks ensure each field receives data in the correct format, within allowed ranges, and consistent with related fields. When you add a second review or double-check, you create an additional safeguard that catches mistakes the automated checks might miss, like a transposed digit or a missing value. Together, these practices provide immediate feedback and human oversight, which substantially lowers the chances of incorrect data making it into records.

Guessing values invites inaccuracy and inconsistency. Entering quickly and correcting later often means errors go unnoticed until later, when they’re harder to fix. Disabling input validation removes the guardrails that prevent many common mistakes in the first place.
