Specs just stating "the data will be averaged out"...
-
Just had a nice bundeled pile of papers dropped on my desk that are supposed to be the specifications of a feature I'm gonna have to implement. Started reading and discovered "the data will be averaged out" as only reference to how data will be manipulated. That's not how I would write the specs, but it's been years since I had my course on statistics at uni, and the fact that I lost my course notes somewhere in between 'temporary' relocations numbers 3 and 7, I'm hoping some of you good folks here could point me towards some good reference material. So, what are the 'need to have' publications in this field? Thanks in advance W.

First, you should confirm how the data is to be averaged. Is the data a constant stream? is it a block of data, is it mean or median, etc. etc. http://en.wikipedia.org/wiki/Average[^] If you are working with a data stream, then you might want to confirm what sort of swing-door algorithm to use, what the deviation and exception criteria would be etc. It is such a woolly statement. Of course if you want the easy option, you could just sum up all the values and divide by how many values there are!

Implement a mode average; that'll bluddy learn 'em.
I wanna be a eunuchs developer! Pass me a bread knife!

Mode of the last two values, that'll even it out and flatten the spikes.
Panic, Chaos, Destruction. My work here is done. Drink. Get drunk. Fall over - P O'H OK, I will win to day or my name isn't Ethel Crudacre! - DD Ethel Crudacre I cannot live by bread alone. Bacon and ketchup are needed as well. - Trollslayer Have a bit more patience with newbies. Of course some of them act dumb - they're often *students*, for heaven's sake - Terry Pratchett

I'm going for the easy option... every set will have an average of 42 Actually the data will be a year worth of call sessions made and durations of those calls. The end results are to be some 'trend' graphs (not me saying this... it's them bloody specs forcing me) and the PM wants to 'flatten' out the graphs... I wanted to read up on statistics and analysis a bit, to be able to counter the PM if he's talking b*ll*cks again...

Recommended textbook on my uni stats course was called "How To Lie With Statistics"[^] by Darrel Huff - a very small book, but very entertaining and enlightning
