Dear gurus,

Im a newbie, and I want to ask a very general question.
Assume that I have a set of numbers as follows,

1, 1, 2, 10, 100, 10,1

From these, I need to identify which number is the most different as
compared to others. (in this case, it will be 100, since its way larger than the other numbers). It doesnt have to be specifically this way, but I need to identify which number(s) are most different compared to the others.

Any idea as to what I need to do this ? Im a math noob, so I'm also going to need to ask it this is called 'standard deviation' or 'variance' :-)

You are requested not to use rhelp as a statistics Q&A list. It was not set up to remediate gaps in statistics education. There are other websites and perhaps mailing list whose purposes would be a better fit for this question.
