Five-Number Summary and Box Plots
Formula
The five-number summary consists of the minimum, first quartile (Q1), median, third quartile (Q3), and maximum. It provides a concise description of a dataset's distribution.
The five-number summary is the foundation of box plots (box-and-whisker diagrams), which visually display the spread, skewness, and potential outliers in data.
Common use cases:
- Quick data distribution overview
- Box plot construction
- Comparing distributions across groups
