In a box plot, the box represents which portion of the data?

• A. The entire dataset
• B. The middle 50%
• C. The top 25%
• D. The bottom 25%

Answer: (B)

The box in a box plot shows the middle 50% of the data. It spans from the first quartile to the third quartile (the 25th to 75th percentiles), often called the interquartile range. The line inside the box marks the median, dividing that central portion into two equal halves. The whiskers extend to the extreme values within 1.5 times the IQR, with outliers shown separately. So the box specifically represents the central half of the data, not the entire dataset or just the top or bottom quarter.
