A boxplot uses which five-number summary?

• A. Mean, Median, Mode, Range, Standard Deviation
• B. Min, Q2, Median, Q4, Max
• C. Minimum, Q1, Q3, Median, Max
• D. Min, Q1, Median, Q3, Max

Answer: (D)

The boxplot is built from the five-number summary: the minimum, first quartile, median, third quartile, and maximum. In a boxplot, the box spans from the first quartile to the third quartile, with a line inside the box at the median. The whiskers reach to the minimum and maximum, showing the full range of the data. This combination gives a quick snapshot of location and spread, and it also hints at skewness by where the median sits inside the box and how long the whiskers are. The five numbers—minimum, Q1, median, Q3, maximum—are exactly the values used. Other options mix in the mean or standard deviation, or use terms like range or a nonstandard quartile, which aren’t part of the five-number summary.
