Studentized Range Distribution: The studentized range \(q\) The Tukey method uses the studentized range distribution. Suppose we have \(r\) independent observations \(y_1, \, \ldots, \, y_r\) from a normal distribution with mean \(\mu\) and variance \(\sigma^2\). Let \(w\) be the range for this set , i.e., the maximum minus the minimum. Now suppose that we have an estimate \(s^2\) of the RANGE applies to the distribution of the studentized range for n group means. PARTRANGE applies to the distribution of the partitioned studentized range. Let the PARTRANGE applies to the distribution of the partitioned studentized range.
