Data cleaning is the process of identifying and correcting errors, inconsistencies, and anomalies in datasets. This includes fixing typos, standardizing formats, and removing irrelevant data.
Common cleaning tasks include removing duplicate records, fixing data type mismatches, standardizing text (capitalization, spacing), and validating against business rules.
Clean data is essential for reliable analysis. Unclean data can lead to biased models and incorrect business decisions.
