Answer Key and Explanations

Check these only after attempting every question.

1. B - a comparison - a target, a previous period, or both

'87% on-time' prompts 'is that good?', which the dashboard then has to answer.

2. B - placement

Top-left is read first, and below the fold is often never read at all.

3. B - can produce a technically true, meaningless headline

Constrain the combinations that produce samples too small to mean anything.

4. B - is not built

Naming what you will not show is what stops a dashboard sprawling.

5. B - a design decision, such as no default view or no hierarchy

Only load time is technical; the rest are decisions made without a decision to serve.

Practical Check

Apply this module to your own work: complete the module activity for *Dashboard Layout, Narrative Flow and Executive Summary*, then write one sentence naming what your result shows and one naming what it does not.

Strong Answer Pattern

A strong answer names the task, the evidence used, the check performed, and the remaining limitation. It avoids "proved", "guaranteed", or "always" unless the evidence genuinely supports it.
