Keeping the world running
Well, leaving out the zeros, the median is 4.
Also, interestingly enough, only 2003,2004,2007, 2010, 2011 show statistical significant in the number of updates per NES, all others fall within the standard error, with 2003,2004, and 2007 being spikes, and 2010 and 2011 being lows. As far as number of updates per NES, one cant say there was a decline until 2010.
Except for in 2003, the number of NESs per year fall within 2 standard deviations (STD = 30.7) of the average (99.4) so its hard to say that there is a statistically significant decline in the number of NESs
Though, I'm sure there is a better probability distribution than normal to fit updates per NES, but I don't remember much from that part of statistics. OTOH, A normal distribution fits NESs per year nicely.
