Using any tools which you would expect to find on a nix system (in fact, if you want, msdos is also fine too), what is the easiest/fastest way to calculate the mean of a set of numbers, assuming you have them one per line in a stream or file?

I was wondering if it's possible to calculate the average of some numbers if I have this: int currentCount = 12; float currentScore = 6.1123 (this is a range of 1 <-> 10). Now, if I receive another score (let's say 4.5), can I recalculate the average so it would be something like: int c…

I have a range of dates and a measurement on each of those dates. I'd like to calculate an exponential moving average for each of the dates. Does anybody know how to do this? I'm new to python. It doesn't appear that averages are built into the standard python library, which strikes me as a lit…

Say you have an array of int (in any language with fixed size ints). How would you calculate the int closest to their mean? Edit: to be clear, the result does not have to be present in the array. That is, for the input array [3, 6, 7] the expected result is 5. Also I guess we need to specify a …
