DA0-001 Communicating Data Insights Practice Question
This DA0-001 practice question tests your understanding of communicating data insights. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An analyst is presenting findings to a non-technical audience. The data shows a 20% increase in customer churn after a price change. Which presentation approach is BEST?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
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 churn before and after
Option C is correct because a simple bar chart visually and intuitively communicates the 20% increase in churn to a non-technical audience without requiring statistical literacy. This approach aligns with best practices for presenting data insights to stakeholders who need clear, actionable takeaways rather than technical details.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Explain the p-value
Why it's wrong here
P-values are statistical concepts that are not accessible to a general audience.
✗
Provide the raw data table
Why it's wrong here
Raw data tables are overwhelming and not immediately interpretable for most audiences.
✓
Use a simple bar chart comparing churn before and after
Why this is correct
A bar chart is simple, visual, and directly shows the comparison without jargon.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Show a complex statistical model
Why it's wrong here
A complex model is too technical and may confuse a non-technical audience.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often overcomplicate the presentation by choosing technical options (like p-values or models) to demonstrate rigor, forgetting that the exam prioritizes audience-appropriate communication over statistical depth.

Detailed technical explanation
How to think about this question
In data visualization, the choice of chart type directly impacts cognitive load; a bar chart leverages pre-attentive processing (e.g., length comparisons) to make differences immediately apparent. For churn analysis, a paired bar chart with clear labels (e.g., 'Before Price Change' vs. 'After Price Change') and an annotation of the 20% increase ensures the insight is retained without requiring the audience to interpret axes or scales. This approach is grounded in principles from Tufte's data-ink ratio, minimizing non-data elements to maximize clarity.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the DA0-001 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
