CompTIA DataX (DY0-001) — Question 23

An analyst wants to show how the component pieces of a company's business units contribute to the company's overall revenue. Which of the following should the analyst use to best demonstrate this breakdown?

Answer options

• A. Box-and-whisker chart
• B. Sankey diagram
• C. Scatter plot matrix
• D. Residual chart

Correct answer: B

Explanation

The Sankey diagram is ideal for displaying the flow and contribution of different components to a total, making it the best choice for illustrating how business units affect overall revenue. In contrast, a box-and-whisker chart is used for statistical distribution, a scatter plot matrix focuses on relationships between variables, and a residual chart is typically for showing residuals in regression analysis, which do not fit this use case.
