Minitab's outliers

Forgive me if this has been discussed already, but I think it hasn't.
My class and I discovered today that when MINITAB draws "modified" box
plots it identifies outliers by some rule other than the 1.5 x IQR's
from Q1 and Q3 that Moore and McCabe and others use. (We got an
oulier on the MINITAB plot that didn't show up on somebody's TI-83.).
Does anybody know what criteria MINITAB uses to identify outliers? I
couldn't find the answer in the documentation (this is Student Minitab
for the Mac, v.8, BTW).

Thanks in advance. Also, thanks to all for your responses to my m &
m between-bag variation concerns.
