I verify data accuracy by running validation checks such as range checks, missing value analysis, and consistency checks across key fields. I reconcile totals against trusted source systems and use historical trends to spot anomalies or sudden breaks. When sources conflict, I first identify the system of record, then investigate differences in definitions, timing, or aggregation logic. I document assumptions, resolve discrepancies with stakeholders, and use the most reliable source while clearly flagging any remaining limitations.
