Decile

A decile is a statistical method of dividing ranked data (largest to smallest or vice versa) set into ten equivalent clusters in which each group is one tenth of the whole population. With this quantitative technique, large data can be easier to analyze. The clusters are denoted as D1, D2, D3 … and so on until D10 with D5 as the median. For instance, in relation to percentile, the 27th percentile is in the second decile.
