Talk:Arithmetic mean
From Wikipedia, the free encyclopedia
I removed this:
- (When used as a noun, the word "arithmetic" is pronounced with the accent on the second syllable, but when used in the present sense, as an adjective, the accent is on the third syllable: "arithMETic".)
This just seems inappropriate to me, and even condescending, but if anybody else wants to put it back, feel free.
- I put it back, but at the end.

[edit] Notation
Is there any simple (i.e. not summation) way to denote a mean of a, b, and c within an expression? The best I know of is: average (a,b,c), which doesn’t even seem half-decent. Would µ or x̅ be used in place of “'average”? (Should µ be italicized in the article?) —Frungi 07:38, 11 February 2006 (UTC)
[edit] Resolution
I have been looking for information on this, but I can't find anything to back it up. I once read another issue w/ arithmetic mean is that you get a false sense of resolution in your measurements. For example, if I am measuring temperature over 10 days and each day I can only measure to the nearest degree (meaning 45 degrees or 46 degrees), then it is possible with a data set of (43, 46, 46, 47, 50, 54, 52, 51, 50, 49) to end up with an average temperature of 48.8, making it seem that I can measure with that level of accuracy, which isn't true. While not a real issue with this case, it can be problematic within the science realm. --ronb 20:33, 7 Feb 2007 (UTC)

Do you guys think maybe this section is a bit cluttered and could stand a small cleanup? --ronb 20:34, 7 Feb 2007 (UTC)
[edit] Empirical mean
Empirical mean redirects here, but the term is not referenced in this page. Is it just a synonym for "Arithmetic mean"? If so, that should be stated. Hv 13:57, 17 February 2007 (UTC)
