CompTIA Data+ (DA0-001) — Question 362

An analyst is working to identify trends in a study and finds the data set has a lot of missing values. Which of the following best describes the data quality issue?

Answer options

• A. Accuracy
• B. Redundancy
• C. Duplication
• D. Completeness

Correct answer: D

Explanation

The correct answer is D, Completeness, as it refers to the extent to which all required data is present. Missing values indicate that the dataset is incomplete, which can hinder analysis. The other options, such as Accuracy, Redundancy, and Duplication, deal with different aspects of data quality that do not directly pertain to missing values.
