DA0-002 Data Governance Practice Question
A data analyst is preparing a data storytelling presentation for a non-technical audience. Which THREE techniques are most effective for communicating insights?
⚠ Common exam trap
A common mix-up: candidates confuse 'data completeness' with 'effective communication,' selecting raw data tables (Option B) thinking they provide transparency, when in fact they hinder comprehension for non-technical stakeholders.

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
✓
Using relevant visuals such as charts and graphs.
Option A is correct because relevant visuals such as charts and graphs translate quantitative findings into patterns a non-technical audience can grasp quickly, which is the core of effective data storytelling. Option D is correct because annotations that call out the most important finding direct audience attention to the key insight instead of forcing them to hunt for it, which sharpens the message. Option E is correct because a clear narrative with a beginning, middle, and end gives the presentation a logical flow that builds context, delivers the insight, and lands the takeaway for non-specialists. Option B does not belong because raw data tables overwhelm non-technical listeners with detail and belong in an appendix rather than the main story. Option C does not belong because complex statistical terminology creates a barrier for a non-technical audience and shifts focus from insight to jargon.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Using relevant visuals such as charts and graphs.
Why this is correct
Relevant visuals translate quantitative findings into patterns a non-technical audience can grasp immediately, satisfying the stem's requirement to communicate insights effectively. Charts and graphs encode comparisons, trends and outliers spatially, bypassing statistical literacy barriers. This makes the insight accessible without requiring the audience to interpret raw tables or numerical summaries.
- ✗
Including raw data tables for reference.
Why it's wrong here
Raw tables force a non-technical audience to interpret numbers themselves, obscuring the insight the narrative should convey. It is tempting because tables appear to add credibility and precision, yet they belong in an appendix; charts and plain-language headlines carry the message instead.
- ✗
Adding complex statistical terms to demonstrate expertise.
Why it's wrong here
Statistical jargon alienates listeners lacking that background, blocking comprehension of the insight rather than demonstrating rigour. It is tempting because precise terminology signals analytical credibility to peers, but it suits a technical review; storytelling for lay audiences needs plain language and visual analogies.
- ✓
Highlighting the most important finding with annotations.
Why this is correct
Annotations draw the audience's eye to the single most decision-relevant data point and state its meaning in plain language, preventing viewers from drawing their own conclusions from an unlabelled chart. This satisfies the stem's non-technical communication requirement.
- ✓
Using a clear narrative with a beginning, middle, and end.
Why this is correct
A beginning, middle and end structure sequences the insight as setup, evidence and recommendation, giving non-technical listeners a logical path through the material. This narrative framing directly meets the stem's requirement for effective communication to a non-specialist audience.
