True- unless one want to tackle procedures in Outliers in Statistical Data
(Wiley Series in Probability & Statistics) 
Vic Barnett , Vic Barnett which costs $228 for the book (gad, I cannot
believe I have that book in my collection).

One should be very cautious about the temptation to hand pick and delete
outliers.

And a reminder that all one needs to do is sort the numbers by any method
and grab the middle one--in UNIX/Linux the "sort" command will do.
