DA0-002 Visualization and Reporting Practice Question
A marketing team wants to explore the relationship between advertising spend (in dollars) and resulting revenue. Which chart type is most suitable?
⚠ Common exam trap
DA0-002 often tests the distinction between chart types for different analytical purposes, so candidates may pick a line chart out of habit for 'trends' when the question asks about the relationship between two variables, which requires a scatter plot.

Correct answer & explanation
✓
Scatter plot
A scatter plot is designed to display the relationship between two quantitative variables, with one variable on the x-axis and the other on the y-axis. Plotting advertising spend against revenue allows the marketing team to visually assess correlation, trends, and outliers. This is the standard chart type for bivariate numerical analysis.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Line chart
Why it's wrong here
A line chart plots a continuous sequence against time, so it shows trends rather than the correlation between two numeric variables. It would be the right choice for tracking advertising spend or revenue across successive months, not for relating spend to revenue.
- ✗
Table
Why it's wrong here
A table lists exact values in rows and columns, forcing readers to compare figures mentally rather than revealing the spend-to-revenue relationship visually. It suits precise lookups of individual records, such as each campaign's spend and revenue, not correlation analysis.
- ✗
Pie chart
Why it's wrong here
A pie chart shows parts of a single whole as proportional slices, so it cannot plot two numeric variables against each other. It would be correct for displaying each channel's share of total advertising budget, not the relationship between spend and revenue.
- ✓
Scatter plot
Why this is correct
A scatter plot positions each observation by two continuous variables, plotting advertising spend on one axis against revenue on the other. This directly satisfies the stem's requirement to explore the relationship between two numeric measures, revealing correlation, clustering and outliers that category-based charts cannot show.
