DA0-002 Data Governance Practice Question
A data analyst is creating a presentation for the board of directors. The board members have varying levels of data literacy. The analyst wants to ensure that the key insight—that customer satisfaction scores have declined by 15% due to longer wait times—is understood by everyone. Which approach is best?
⚠ Common exam trap
Test-takers frequently confuse 'more data' with 'better communication'—candidates may pick the scatter plot or statistical model because they seem more rigorous, but the exam tests audience-appropriate visualization, not analytical depth.

Correct answer & explanation
✓
Use a simple annotated line chart with a clear callout on the decline.
A simple annotated line chart with a clear callout directly communicates the trend (15% decline) and the causal factor (longer wait times) without requiring statistical literacy. Board members with varying data literacy need a visual that highlights the 'so what' immediately, and annotation removes ambiguity about which part of the chart matters. This aligns with best practices for executive dashboards: one message per chart, minimal cognitive load, and explicit labeling of the insight.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Include a complex statistical model showing the correlation.
Why it's wrong here
A complex statistical model demands technical interpretation, obscuring the 15% decline for board members with limited data literacy. It is tempting because such models are the correct choice when the audience comprises statisticians who need to validate significance, confidence intervals and model fit.
- ✗
Show a scatter plot of wait time vs. satisfaction.
Why it's wrong here
A scatter plot shows correlation between wait time and satisfaction but requires statistical interpretation to read the 15% decline, which low-literacy board members may miss. It is tempting because scatter plots are the correct choice when analysts must examine relationship strength and outliers.
- ✗
Provide raw data in a spreadsheet for review.
Why it's wrong here
Raw spreadsheets require recipients to interpret and aggregate figures themselves, so the 15% decline is not conveyed to low-literacy board members. It is tempting because spreadsheets give full detail and support drill-down, which suits analytical reviewers verifying figures rather than executives needing a summary.
- ✓
Use a simple annotated line chart with a clear callout on the decline.
Why this is correct
An annotated line chart shows the trend over time, and the callout directs every reader to the 15% decline regardless of data literacy. This satisfies the need to communicate one key insight simply and unambiguously to a mixed audience.
