What is Data Cleanup?
Data cleanup is the process of identifying and resolving quality issues in a dataset before analysis. Raw data from real-world sources almost always contains errors, missing values, duplicates, and inconsistencies. Thorough cleaning ensures that analysis results reflect reality rather than artifacts of data collection.
