Plot the data so we can see that it is not an outlier. But wait. It can be seen as Trend if you cut the timeline short enough. My goodness honton.
I know you are right that it is not an outlier if you look about 6 months back. Yeah for that time you can see a downward trend. But why does that matter for a software project that dates back many years and over this period shows a stable devleloper count of 200 +/-50?
Compare 2006 and 2012 - both around 200. But that does not matter also, because it is cherry picking numbers. We see an upward trend until 2010, then a drop, then stable for 2 years. Then a small drop for 2013.
But I guess Iīll have to do another plot containing ALL data myself for you, because all the interesting questions and tasks other people here give you, you just evade... sigh. You seem to be a pretty lazy guy, are you?
Thank you too. You have proven to be lazy and to evade questions and sources.
Here the kde-dying-graph with monthly values (not means). For you honton, because you do not seem to believe in math or statistics. yeah definitely dying. and so quickly. almost like the titanic.
and yes, the 121 is not included because I took only the first value of every month. shame on me
