Finding Max and Min while ignoring a specific range

Hi All,
I am trying to find the max/min of a single column of data. Normally I would use the max(X) and min(X), but this particular dataset has spikes I'd like to ignore. The values tend to be roughly -.010 < X < .010, but there are some instantaneous spikes within the data around +/-100. Is there a way to get the max and min while ignoring these spikes?
For example:
If X < 1 AND X > -1 Then max(X) AND min(X) Else Ignore
Hope this makes sense. Thanks in advance for your help! -Marcus

max( X( X < 0.01 ) )
min( X( X > -0.01 ) )
should work?

You could try running a non-aggressive smoothing filter to try to get ride of the outliers, but that will diminish your magnitudes elsewhere too. You can't really do much without getting rid of the erroneous data though.
