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.
