What is data verification?

Data verification is the process of ensuring the accuracy and reliability of information by cross-checking it against various sources or validating it through predefined criteria. This crucial step aims to enhance data quality and trustworthiness.

How can you verify data?

  • Sampling. Select a representative data sample to identify patterns and trends, verifying accuracy.
  • Field checks. Verify data accuracy in specific fields or columns.
  • Cross-referencing. Compare data from multiple sources to ensure consistency and accuracy.
