Explanation

ETL stands for Extract, Transform, Load. The Transform phase includes data cleaning activities such as identifying and handling missing values, standardizing formats, removing duplicates, and correcting errors. Creating dashboards and pivot tables are data visualization/reporting activities that happen after ETL. 'Multiplying unique data' is not a recognized ETL concept. Handling missing values is a core transformation step before data is loaded into a target system.
