Table 1

In statistics, a decile is one of ten segments of a distribution that has been divided into tenths.[1] The first decile is the first tenth, the second decile is the second tenth, and so on. In probability, a decile is a portion of probability distribution that is divided into ten parts with equal areas[2].

Table 1 shows a set of scores and their percentile, decile and quartile rankings.
