$ q = \displaystyle \frac {\text{the difference between any two means}}{\text{the standard error of the difference between any two means}} $
$ q = \displaystyle \frac {\overline{X_i}-\overline{X_j}}{\text{se}} $
$ se = \displaystyle \sqrt{ \frac {Var_{by error}}{n} } $
$ se = \displaystyle \sqrt{ \frac {MS_{error}}{n} } $
cf.
$ t = \displaystyle \frac {\text{the difference between any two means}}{\text{the standard error of the difference between the two means}} $
