⚠ Common exam trap
Many exam-takers choose Option D because it is technically accurate, but the exam tests the ability to tailor communication to the audience's data literacy, not just technical correctness.

Correct answer & explanation
✓
Explain that the whiskers show the range of typical scores, like the spread of data.
It uses plain language ('range of typical scores') to explain whiskers to a non-technical audience, aligning with the DA0-001 domain of communicating data insights effectively. The whiskers in a box plot typically extend to the minimum and maximum values within 1.5 times the interquartile range (IQR), representing the spread of data without outliers, which is accurately described as 'typical scores' for stakeholders who are not data-savvy.
