Which technique can be used to ensure data accuracy and verification?

Using visual checking and double entry is an effective technique for ensuring data accuracy and verification. This approach involves entering the same data twice, either by the same person or different individuals, and comparing the results to identify any discrepancies. The double entry system serves as a safeguard, as it highlights errors that may be overlooked during single entries, thus enhancing the integrity of the data.

Visual checking adds an additional layer of verification, as it allows individuals to spot and correct errors that might occur during data input. By visually reviewing the data, one can catch inconsistencies or mistakes that automatic systems might miss, making it a comprehensive method for maintaining data accuracy.

The technique combines both human oversight and systematic checks, which together contribute to a robust data management strategy. Other options like relying solely on one method of data entry or automated error reports do not incorporate the thoroughness and reliability of additional verification measures, while single verification systems lack the redundancy that double entry provides.
