The Decile function computes the specified decile of the specified random variable or data set.

The first parameter can be a data set (e.g., a Vector ), a Matrix data set , a distribution (see Statistics[Distribution] ), a random variable, or an algebraic expression involving random variables (see Statistics[RandomVariable] ).

The second parameter d is a decile or list of deciles.

For a description of the available options, see the Statistics[Quantile] help page. Calling Decile with decile $d$ is equivalent to calling Quantile with probability $0.1d$.
