DA0-002 Data Governance Practice Question
A healthcare company's data analyst is tasked with presenting patient readmission rates to a group of doctors and nurses. The data shows that readmission rates are higher among patients with certain chronic conditions. The audience has limited data literacy, but they are familiar with clinical terms. The analyst wants to communicate the insights effectively and encourage discussion on preventive measures. The presentation will last 15 minutes, and the audience expects actionable insights. What should the analyst do?
⚠ Common exam trap
CompTIA often tests the principle that the best visualization for an audience with low data literacy is the simplest one that directly maps the insight, and the trap here is that candidates may overcomplicate the choice by selecting a scatter plot (Option D) because it looks 'analytical,' even though it fails to address the specific categorical comparison needed.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a simple bar chart comparing readmission rates by condition.
A simple bar chart directly compares readmission rates across chronic conditions using a visual format that is intuitive for an audience with limited data literacy. It avoids overwhelming them with raw numbers or complex statistical outputs, enabling quick comprehension and fostering discussion on actionable preventive measures within the 15-minute timeframe.

Why it's wrong here
Not visually impactful; difficult to see patterns quickly.
- ✗
Show a complex regression model output to demonstrate correlation.
Why it's wrong here
Too technical for audience with limited data literacy.
- ✓
Use a simple bar chart comparing readmission rates by condition.
Why this is correct
Clearly shows which conditions have highest readmission, enabling discussion.
- ✗
Show a scatter plot of age vs. readmission rate.
Why it's wrong here
Does not directly address chronic conditions and may be confusing.
