Quintile is a mathematical term used to describe dividing a group of things or people into five equal parts. For example, if you have a group of students and you want to rank them based on their test scores, you could divide them into five groups, with the top 20% in the first quintile, the next 20% in the second quintile, and so on. This term is commonly used in statistics and research to analyze data, but may not be used in everyday conversation.
