Decile
Decile
Decile (/ˈdɛsaɪl/ or /ˈdɛsɪl/) is a statistical term used to describe a specific position in a set of data. The term is derived from the Latin word "decimus", meaning "tenth".
A decile divides a data set into ten equal parts, with each part containing 10% of the data. The first decile, for example, represents the lowest 10% of the data, while the tenth decile represents the highest 10%.
Deciles are commonly used in a variety of fields, including economics, statistics, healthcare, and education. They are particularly useful for understanding the distribution of data and identifying outliers.
