Studentized range

In statistics, the studentized range computed from a list x₁, ..., xn of numbers is

Failed to parse (syntax error): {\displaystyle \frac\max\{\,x_1,\dots,x_n\,\} - \min\{\,x_1,\dots,x_n\,\}}{s}, }

where

Failed to parse (syntax error): {\displaystyle s^2 = \frac{1]{n - 1}\sum_{i=1}^n (x_i - \overline{x})^2, }

and

${\overline {x}}={\frac {x_{1}+\cdots +x_{n}}{n}}$

is the sample mean.
