CompTIA Data+ (DA0-001) — Question 253

A data analyst is working with a data set and would like to combine two fields into a single field. Which of the following data manipulation techniques should the analyst use?

Answer options

• A. Data merge
• B. Transpose
• C. Data append
• D. Concatenation

Correct answer: D

Explanation

The correct answer is D, Concatenation, as this technique specifically combines two or more fields into a single field. Options A (Data merge) and C (Data append) involve different processes of combining data sets rather than merging fields, while B (Transpose) reorganizes data rather than merging fields.
