CompTIA Data+ DA0-002 (V2) Practice Question

The correct answer is to manually calculate the metric for a small, representative data sample and compare it to the report's output. This is the most direct way to perform a calculation review ('Review > Calc'), as it isolates the formula and its logic to verify its correctness against a known outcome. Peer review is a valid technique but is less direct than validating the calculation oneself. Filtering the data to exclude returns would change the underlying data and prevent the analyst from fixing the actual calculation logic. Rerunning an ETL job is a source validation technique, but the scenario states the source data has already been confirmed as accurate.
