Show answer & explanationAnswer & explanation
Correct answer: C. Employing progressive disclosure with clear summaries and optional details.
Progressive disclosure involves presenting core information first, then allowing users to access more detailed or complex data only if they choose to. This approach ensures non-technical stakeholders grasp the main insights without being overwhelmed, while technical specialists can delve into the underlying details if necessary.
Why the other options are wrong
- A. Focusing solely on granular data would make it difficult for non-technical users to see the bigger picture or overarching insights.
- B. Using highly specialized charts would alienate non-technical stakeholders, defeating the purpose of a diverse audience.
- D. Displaying all statistical formulas and raw outputs would overwhelm non-technical audiences and obscure key findings.
Progressive Disclosure
A design principle that defers advanced or less frequently used features and information to a secondary screen or interaction, showing only the essentials upfront.
- Manages complexity by hiding details until needed.
- Reduces cognitive load for the general user.
- Allows users to delve deeper if they choose.
- Especially useful for diverse audiences with varying technical expertise.
