There doesn't exist such things:

I think you're looking for PERCENTILES.

Programs for Standard Deviation

[Robert Meyer]

My daughter has asked me if there are any tools / software programs that can
resolve standard deviations, while Excel can determine a standard deviation
of the Population, what formula is used for the
(A) 5th Standard Deviation
(B) 10th Standard Deviation
(C) 25th Standard Deviation
(D) 40'th Standard Deviation
My Intro to Stat's and Probability , Stats for Business and Economics, and
Elements of Probability Textbooks
have no data on these.  If you can either point me to a web page, know the
formula, or where I can locate the software I would appreciate{:->

Thanks

over and above

[dennis roberts]

grading projects for a first assignment REreminds me that ... some students 
go way above and beyond the call of duty when doing projects ... in my 
case, they have to download a file ... do some analyses ... and then do 
some write up of what they found.

now, some go to alot to trouble to do very nice documents in a word 
processor and have gone to fancy extents ... whereas others will use 
(minitab is the package in this case) minitab ... and do all their work in 
it (which is possible) and turn in an acceptable document ... say the right 
things, etc.

the QUALITY of the document is not a gradable criterion (in my system ... 
maybe it should be) ... but, how do any of you deal with this sort of thing 
... whether it be a document to be turned in or some other assignment ... 
some just go WAY over what is required ...

of course, penn state has no A+ grade category .. !!!

This is so dangerous that it needs total condemnation.

Keyboards, computers, calculators, etc., are only tools.
Whether or not they are needed is a matter of the local
situation, and not of any real relevance.
