Which data quality characteristic ensures that all data items are included in the collected information?

Comprehensiveness is the data quality characteristic that ensures all data items are included in the collected information. This means that the dataset is complete and contains all necessary information relevant to the topic being studied. When data is comprehensive, it accounts for all possible variables and scenarios, which is crucial for analysis and making informed decisions.

A comprehensive dataset allows for thorough analysis by providing a full scope of information, minimizing gaps that could lead to misleading conclusions. This characteristic is essential in fields like healthcare, where complete patient records are vital for quality care and effective treatment outcomes. Comprehensiveness ensures that researchers, analysts, and decision-makers have access to all pertinent data, which supports accurate evaluations and insights.
