Which feature of a box-and-whisker plot shows the median?

• A. The whiskers
• B. The box
• C. The central line
• D. The outliers

Answer: (C)

The central line inside the box marks the median—the middle value that splits the data into two halves. In a box-and-whisker plot, the box itself spans from the first quartile to the third quartile (the middle 50% of the data), and the line inside the box shows the median. The whiskers reach the extreme non-outlier values, and any points beyond them are outliers. So this feature is the best indicator of the median because it directly represents that middle value where half the data lie below and half above.
