Data normalization requires repeated groups to be deleted from the same column, not from the same row. This is because normalization aims to eliminate redundant data and ensure data consistency, which can be achieved by organizing data into separate tables with each table containing a distinct set of related information. Repeated groups within a column can be removed by creating a separate table for the related information and referencing it through a foreign key.
