CompTIA Data+ (DA0-001) — Question 54

While reviewing survey data, a research analyst notices data is missing from all the responses to a single question. Which of the following methods would BEST address this issue?

Answer options

• A. Replace missing data.
• B. Remove duplicate data.
• C. Replace redundant data.
• D. Remove invalid data.

Correct answer: C

Explanation

The correct method to address the missing data is to replace it, ensuring that the analysis remains robust and valid. Removing duplicates or invalid data does not directly solve the issue of missing responses, and replacing redundant data may not apply in this context.
