What is the key descriptive statistic that a boxplot does NOT provide?

• A. Median
• B. First quartile
• C. Standard deviation
• D. Maximum

Answer: (C)

A boxplot, also known as a whisker plot, is a graphical representation of a dataset that summarizes key statistics regarding the distribution of the data. The components of a boxplot include the median, first quartile, third quartile, and the minimum and maximum values. The median represents the middle value of the dataset when it is ordered from least to greatest, while the first quartile indicates the value below which 25% of the data fall. Likewise, the maximum provides insight into the highest data point in the dataset. However, the standard deviation, which measures the dispersion or variability of a dataset around the mean, is not depicted in a boxplot. This is because a boxplot focuses on the five-number summary (minimum, first quartile, median, third quartile, and maximum) and does not provide specific information about the spread of the data in terms of how much the values deviate from the mean. Therefore, the correct answer highlights the fact that standard deviation is not represented in a boxplot.
