What is included in the five-number summary of a dataset?

• A. Mean, Median, Mode, Range, Variance
• B. Minimum, Q1, Median, Q3, Maximum
• C. Median, Standard Deviation, Maximum, Minimum, Interquartile Range
• D. Minimum, Maximum, Mean, Standard Deviation, Variance

Answer: (B)

The five-number summary of a dataset consists of the minimum value, the first quartile (Q1), the median (the second quartile), the third quartile (Q3), and the maximum value. This summary provides a quick snapshot of the data distribution and helps to understand its spread and center. The minimum value is the smallest data point, while the maximum is the largest. The first quartile (Q1) indicates the value below which 25% of the data falls, and the third quartile (Q3) shows the value below which 75% of the data falls. The median represents the midpoint of the dataset, where half of the data points are below and half are above it. Together, these five measures help to grasp the essential characteristics of a dataset, including its range and central tendency. Other choices listed do not align with the five-number summary as they either include measures not part of this summary or mix them incorrectly. For example, options that mention the mean, mode, variance, or standard deviation introduce concepts of average and variability that go beyond the five-number summary's focus on specific percentile points of the dataset.
