Talk:Averages/Arithmetic mean: Difference between revisions

 

:: Well, that's kinda the point: average of nothing really is a mistake and should be flagged as such. If it doesn't matter in your application, then any return value makes as much sense as another, so there's no need to single out 0 there--"any action you see fit" is a super set of "return 0" anyway. Think it this way, what if the task says "you may return 42"? It's also fair because everyone would then be equally disadvantaged. --[[User:Ledrug|Ledrug]] 22:35, 7 May 2012 (UTC)
