Running average/sum questions

[Quentin]

Hi, this is really basic but the answer eludes me - I want to make a module that creates a running average and a total sum- I have an integer value and a trigger for each time I want to collect a value to include in the sum and running average. I guess essentially I need to perform x=x+n each time the trigger goes.. Sorry if I am missing something obvious..
Thanks

Thanks for the example, my problem that I don't want to build a huge array, just want to accumulate the sum of the values over a long period of time, sorry I realized after I posted that I should have explained this detail. Thanks again for the response..

Hi Quentin,
This example should do what you want without eating up unnecessary memory...

Thanks so much, that is exactly what I was in the process of trying to piece together in ruby- I am new to ruby so it's slow going for me- so your timing could not be better with that example..
