Verification is performed after cleaning to ensure what?

Verification after cleaning is about confirming that the dataset is accurate, complete, and consistent once the cleanup steps are done. It involves applying quality checks, comparing samples or the whole set to source or trusted references, validating against business rules, and ensuring values and formats meet expected standards. This ensures the cleaned data can be trusted for analysis and decision-making. The other activities—forecasting future trends, transferring data to a data warehouse, or anonymizing data for privacy—are separate tasks and not the purpose of verification after cleaning.
