Comprehensive and Detailed In-Depth Explanation:
In data management,duplicate datarefers to identical records that appear multiple times within a dataset. Such duplicates can lead to inaccurate analyses, inflated metrics, and erroneous business decisions. Identifying and removing duplicate records is a critical step in the data cleansing process to ensure data quality and reliability.
Option A:Duplicate data
* Rationale:The dataset shows that the record with ID 376, Amount $400, and SKU ABV-DYH appears twice. This repetition indicates the presence of duplicate data, which can skew analysis results if not addressed.
Option B:Imputed data
* Rationale:Imputed data refers to missing or incomplete data that has been estimated or filled in based on other available information. There is no evidence in the provided dataset to suggest that any data has been imputed.
Option C:Redundant data
* Rationale:Redundant data involves unnecessary repetition of data across different fields or tables, leading to inefficiencies. While duplicate data is a form of redundancy, in this context, the specific issue is the exact repetition of entire records, making "duplicate data" the more precise term.
Option D:Corrupt data
* Rationale:Corrupt data refers to data that has been altered or damaged, making it incorrect or unusable.
The dataset provided does not exhibit signs of corruption, such as garbled text or invalid formats.
