Data completeness

Definition

Data completeness refers to the extent to which all required data is present and available for analysis, ensuring that datasets are not missing critical information. This concept is crucial for accurate analysis and decision-making, as incomplete data can lead to skewed results and misinformed business strategies. Ensuring data completeness involves assessing data sources, identifying gaps, and implementing processes to collect missing information.
