About Quartiles
Quartiles divide a ranked dataset into four equal parts. Each quartile represents 25% of the data:
- Q1: 25% of values are below this point
- Q2: The median - 50% of values are below this point
- Q3: 75% of values are below this point
Quartiles are useful for understanding the distribution and spread of data.
