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)
After this it gets more complicated, but it you're new here let's take it one step at a time
