Sampling Surveys
Data completeness refers to the extent to which all required data is present and accounted for in a dataset, ensuring that the information collected is thorough and usable. This concept is crucial because missing or incomplete data can lead to biased results, inaccuracies in analysis, and ultimately flawed conclusions. Understanding data completeness involves recognizing various forms of nonresponse that can affect the integrity of the dataset, influencing the reliability of the insights drawn from it.
