DA0-002 Data Governance Practice Question
A data analyst is preparing a presentation for executive leadership. The analyst wants to highlight the correlation between marketing spend and revenue over the past year. Which visualization type is most appropriate for showing this relationship?
⚠ Common exam trap
Test-takers frequently confuse a bar chart or histogram with a scatter plot because they think any chart with axes can show relationships, but only a scatter plot directly plots paired continuous data to reveal correlation without aggregation.

Correct answer & explanation
✓
Scatter plot
A scatter plot is the most appropriate visualization for showing the relationship between two continuous variables—marketing spend and revenue—because it plots individual data points on an X-Y axis, allowing the analyst to visually assess correlation, trends, and outliers. This directly supports the goal of highlighting correlation, as the pattern of points (e.g., upward slope) indicates the strength and direction of the relationship.
