Which items are identified by a DEOCS data quality check?

• A. Incomplete responses
• B. Inconsistent items
• C. All of the above
• D. Potential biases in results

Answer: (C)

DEOCS data quality checks look for issues that affect how trustworthy and usable the responses are. Incomplete responses indicate missing data that can skew results or reduce reliability. Inconsistent items show up when answers don’t align across related questions or when there are mis-keyed or ambiguous items, signaling measurement problems. Potential biases in results capture patterns like social desirability or other response biases that can distort what the data truly reflect. Since a quality check flags all of these kinds of issues, it identifies incomplete responses, inconsistent items, and potential biases, meaning all of the above are identified.
