What are the five components of a box plot?

• A. Mean, median, mode, and range
• B. Minimum, lower quartile, median, upper quartile, and maximum
• C. Upper bound, lower bound, average, count, and range
• D. Minimum, lower quartile, median, upper quartile, and maximum

Answer: (D)

This question is about the five-number summary used in a box plot. A box plot shows five key values: the minimum, lower quartile (Q1), median, upper quartile (Q3), and maximum. The box stretches from Q1 to Q3 with a line at the median, and the whiskers reach the smallest and largest data points (or they may show outliers as separate dots beyond the whiskers).

So the five components are minimum, lower quartile, median, upper quartile, and maximum. The other options mix in measures like mean, mode, or counts, which aren’t part of the five-number summary.
