CompTIA Data+ (DA0-001) — Question 201

Which of the following should an analyst do to best summarize the data on a data set?

Answer options

• A. Filtering
• B. Aggregation
• C. Sorting
• D. Concatenation

Correct answer: B

Explanation

The correct answer is B, Aggregation, as it involves combining multiple data points to provide a summary view, which is essential for analysis. Filtering, Sorting, and Concatenation do not inherently summarize data; filtering narrows down data, sorting organizes it, and concatenation combines data without summarizing.
