CompTIA Data+ (DA0-001) — Question 310

Which of the following data manipulation techniques should an analyst use to hide unnecessary data during analysis?

Answer options

• A. Filtering
• B. Parametrization
• C. Sorting
• D. Indexing

Correct answer: A

Explanation

Filtering is the correct answer because it specifically allows analysts to exclude data that is not needed for their analysis, thereby enhancing focus on relevant information. Parametrization, sorting, and indexing do not inherently serve the purpose of hiding data; rather, they are used for organizing, structuring, or accessing data more efficiently.
