Which description best describes a visual check?

• A. It is an automated test run by software.
• B. It is a manual inspection of data to spot obvious errors.
• C. It uses statistical sampling to verify entries.
• D. It validates data against a schema automatically.

Answer: (B)

Visual check means a person looks over the data with their eyes to spot obvious mistakes. It’s a manual inspection, not something produced by software or automatic rules, and it’s best for catching obvious typos, formatting inconsistencies, or clearly out-of-place values that jump out when you glance at the data. The other options describe automated tests, statistical sampling, or schema validation—processes that don’t rely on a human visually inspecting the data.
