What does the five-number summary consist of?

The five-number summary is a concise statistical description that provides a quick overview of a dataset's distribution. It consists of five specific values:

1. The minimum value, which represents the smallest observation in the dataset.
2. The first quartile (Q1), indicating the value below which 25% of the data falls.

3. The median (Q2), which is the middle value of the dataset when arranged in ascending order, representing the 50th percentile.
4. The third quartile (Q3), showing the value below which 75% of the data falls.
5. The maximum value, which is the largest observation in the dataset.

This summary is useful for understanding the spread and center of the data while identifying potential outliers. Each of the other answer choices includes terms that may be related to statistics but do not accurately capture the concept of the five-number summary. They either introduce additional measures that are not part of this summary or mix different concepts that are not relevant to the five-number summary format.
