Statistics[Quartile] - compute quartiles
Calling Sequence
Quartile(A, q, ds_options)
Quartile(X, q, rv_options)
Parameters
A
-
Array or Matrix data set; data sample
X
algebraic; random variable or distribution
q
algebraic; quartile
ds_options
(optional) equation(s) of the form option=value where option is one of ignore, method, or weights; specify options for computing the quartile of a data set
rv_options
(optional) equation of the form numeric=value; specifies options for computing the quartile of a random variable
Description
The Quartile function computes the specified quartile of the specified random variable or data set.
The first parameter can be a data set (represented as an Array or 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 q is the quartile.
Options
For a description of the available options, see the Statistics[Quantile] help page. Calling Quartile with quartile is equivalent to calling Quantile with probability .
Compatibility
The A parameter was updated in Maple 16.
Examples
Compute the quartile of the Weibull distribution with parameters a and b.
Use numeric parameters.
Generate a random sample of size 100000 drawn from the above distribution and compute the sample quartile.
Consider the following Matrix data set.
We compute the third quartile of each of the columns.
