Seriously if outliers are creating such an impact you need to reconsider what it means to manage performance and now it is...]]> Wed, 21 Nov 2012 00:29:52 -0500 Wed, 21 Nov 2012 00:29:52 -0500 Wed, 21 Nov 2012 00:29:52 -0500 Nov 21, 2012 wlouth 0 http://www.theserverside.com/discussions/thread.tss?thread_id=69997 An average used as a measure of central tendency is mostly incorrect for many software measures. The measures can be static or dynamic (as mentioned in the post). Static measures that represent size/complexity (e.g., LOC, vg) follow power-law...]]> Tue, 20 Nov 2012 23:28:30 -0500 Tue, 20 Nov 2012 23:28:30 -0500 Tue, 20 Nov 2012 23:28:30 -0500 Nov 20, 2012 Stephane Vaucher 2 http://www.theserverside.com/discussions/thread.tss?thread_id=69997 Much of the argument can be addressed using "moving averages"

They are simple to understand and calculate. We tend to ignore just how wrong the picture is that averages paint of the world. To emphasis the point let me give you a...]]> Thu, 15 Nov 2012 23:50:13 -0500 Wed, 14 Nov 2012 11:14:08 -0500 Thu, 15 Nov 2012 23:50:13 -0500 Nov 15, 2012 Michael Kopp 5
