About this quiz
What you’ll practice
Misleading visuals often look “professional” while quietly distorting the story. In this quiz, you’ll practice identifying what’s wrong and selecting the most responsible fix.
Each question is multiple-choice with 4 options and no timer, so you can slow down and reason through the design choices.
Common traps to watch for
- Truncated or inconsistent axes that exaggerate change
- Dual y-axes that imply relationships that aren’t there
- 3D effects, area/volume distortion, and perspective bias
- Color choices that hide categories or create false emphasis
- Cherry-picked ranges, bins, or smoothing that changes the narrative
- Misleading labels, ordering, or missing context (units, source, baseline)
Difficulty and how to use it
Difficulty is mixed on purpose: easier items focus on obvious scale and labeling issues, while harder ones test nuanced choices like aggregation, uncertainty, and appropriate chart types.
Before you start, choose your preferred question count and a difficulty setting to tailor the session - short and focused for review, or longer for full-skill coverage.
