DA0-002 Visualization and Reporting Practice Question
A dashboard designer is building a sales performance dashboard for executives. According to dashboard design principles, which TWO practices should be applied? (Choose two.)
⚠ Common exam trap
DA0-002 often tests the misconception that 'more data and decoration equals better dashboards,' tricking candidates into selecting options that add clutter (excessive precision, chartjunk) or remove essential context (no titles/labels), when the correct principles emphasize clarity, consistency, and hierarchy.
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 color coding consistently to group related metrics
Option A is correct because consistent color coding lets executives instantly associate related metrics (e.g., all revenue measures in one hue) and compare them without reinterpreting the legend on each visual. Option B is correct because visual hierarchy—using size, position, and contrast to emphasize the single most important KPI—directs the executive's eye to the critical number first, which is a core dashboard design principle. Option C is wrong because titles and labels are essential for context and self-service interpretation; removing them creates ambiguity. Option D is wrong because excessive precision clutters the display and slows comprehension—executives need rounded, decision-relevant values. Option E is wrong because chartjunk (decorative, non-data elements) distracts from the message and violates the principle of maximizing the data-ink ratio.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use color coding consistently to group related metrics
Why this is correct
Consistent colour coding assigns the same hue to related metrics across every chart, so executives instantly group categories without re-reading labels. This satisfies the design principle of reducing cognitive load, letting viewers compare sales metrics rapidly rather than decoding inconsistent palettes.
- ✓
Use visual hierarchy to make the most important metric prominent
Why this is correct
Visual hierarchy sizes and positions the most important metric, such as total revenue, largest and top-left, so executives grasp performance within seconds. This satisfies the design principle of prioritising information, guiding the eye to the primary sales figure before secondary breakdowns.
- ✗
Avoid titles and labels to keep the dashboard clean
Why it's wrong here
Removing titles and labels leaves executives unable to interpret metrics or context, violating clarity principles. It is tempting because minimalism can reduce clutter, and it works for highly familiar single-metric displays, but unlabelled charts fail when audiences need quick comprehension.
- ✗
Include excessive precision on all numbers to show accuracy
Why it's wrong here
Excessive precision clutters executive dashboards and obscures trends, contradicting the principle of summarising data at the audience's level. It is tempting because precision suggests rigour, and it suits detailed operational or analytical reports where exact figures matter, not executive summaries.
- ✗
Maximize chartjunk to make the dashboard visually appealing
Why it's wrong here
Chartjunk adds decorative elements that distract from the data, contradicting the principle of maximising the data-ink ratio. It is tempting because visual appeal can aid engagement, and styling suits marketing or presentation graphics, but executive dashboards require clarity over ornamentation.
