No it's an outlier problem, I think. If you have a fairly small number of sets of these numbers simple visual inspection of a boxplot for each set would probably acomplish what you want.
Try this in R for an example. Just paste the next two lines into R xx <- c(1, 1, 2, 10, 100, 10,1) boxplot(xx) After this it gets more complicated, but it you're new here let's take it one step at a time John Kane Kingston ON Canada > -----Original Message----- > From: suranga...@gmail.com > Sent: Thu, 1 Mar 2012 09:30:59 -0800 > To: r-help@r-project.org > Subject: [R] Standard variance / devistion clarification > > 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.
