Since PassengerId serves as the primary key for this dataset, this means there are no exact duplicate rows.\n\nFor near-duplicates (rows that differ only in minor fields like timestamps or batch IDs), the presence of unique PassengerIds across all 891 rows indicates that each record represents a distinct passenger. The dataset contains no redundant entries."
