Multiple Choice

Which statement about verification is correct?

Verification is the step where you confirm that the data you’ll analyze is accurate and trustworthy after you’ve cleaned it. It involves checks that the data matches expected values, business rules, and known sources. For example, you might compare a sample of records to the original source documents, verify totals against the source, or run validation tests to catch remaining inconsistencies. This focus on accuracy and reliability distinguishes verification from other data tasks. Outlier removal is a cleaning task that alters data to reduce extreme values; merging datasets is data integration; creating visualizations is about presenting data. Those activities occur before or alongside verification, but verification itself is about confirming that the cleaned data is correct and dependable.
