What is a Five Number Summary?

A Five Number Summary is a statistical tool that provides a quick snapshot of the distribution of a data set. It consists of:

1. Minimum: The smallest data point in the set.
2. First Quartile (Q1): The median of the lower half of the data, representing the 25th percentile.
3. Median: The middle value when the data is arranged in ascending order, representing the 50th percentile.
4. Third Quartile (Q3): The median of the upper half of the data, representing the 75th percentile.
5. Maximum: The largest data point in the set.

This summary is particularly useful for identifying the spread and central tendency of your data, as well as for detecting outliers.
