It is a simple but crude measure of the spread of data.

Quartiles are used in real life to analyze data distributions and make informed decisions. For example, in education, they can help assess student performance by categorizing test scores into quartiles, allowing educators to identify students who may need additional support. In finance, quartiles can be used to evaluate investment performance, helping investors understand how a particular asset compares to others in the market. Overall, quartiles provide valuable insights into data trends and help identify outliers.
