CompTIA Data+ (DA0-001) — Question 341

A data analyst added some missing data to a list of observations, since only a small amount of the data was absent. Which of the following actions did the data analyst perform?

Answer options

• A. Concatenate
• B. Parse
• C. Append
• D. Merge

Correct answer: C

Explanation

The correct answer is C, Append, as this action involves adding new data to an existing dataset. The other options do not fit the context: Concatenate refers to linking data together, Parse involves analyzing data structure, and Merge combines two datasets into one, which isn’t the case here.
