DA0-002 Visualization and Reporting Practice Question
A data analyst needs to present the correlation between advertising spend and website traffic. Which chart type is most appropriate?
⚠ Common exam trap
Candidates often choose a line chart because they mistakenly think 'correlation' implies a trend over time, but the DA0-001 exam specifically tests that scatter plots are the standard for bivariate correlation analysis without a temporal component.

Correct answer & explanation
✓
Scatter plot
A scatter plot is the most appropriate chart type for visualizing the correlation between two continuous variables, such as advertising spend and website traffic. It displays individual data points on a Cartesian plane, allowing the analyst to assess the strength, direction, and form of the relationship (e.g., linear, non-linear, or no correlation). This aligns with the DA0-001 objective of selecting the correct visualization for bivariate analysis.
