Spot Misleading Visuals Quiz

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.
