Which techniques can be employed to ensure data accuracy?

The best choice for techniques to ensure data accuracy includes visual checking, double entry, reading aloud, and triangulation.

Visual checking involves reviewing data visually to catch potential errors or inconsistencies, ensuring that the recorded information aligns with reality. Double entry requires entering the same data twice by different operators to cross-verify accuracy, allowing for the identification of discrepancies. Reading aloud is a technique where data is read out loud to catch errors that might be overlooked during silent review, as auditory processing can help identify mistakes. Triangulation involves using multiple methods or sources to verify the same data, enhancing validity and reducing the likelihood of errors.

These techniques are specifically geared towards improving data quality by systematically addressing potential inaccuracies through careful verification and validation processes. In contrast, the other options primarily focus on data analysis, interpretation, or collection methods, which do not directly relate to the processes necessary for ensuring data accuracy.
