adjusting the task to give languages a chance to show them? --[[User:Paddy3118|Paddy3118]] 16:10, 2 July 2011 (UTC)
:Which part of it looks like a challenge? You add up some numbers, then maybe divide by another number, it's not like there's tricky coding to be done. Large dataset is a real senario and not hard to deal with, as long as you don't artificially complicate it. And as sample size increases, numbers such as mean and stddev becomes stable, which is almost the whole point of statistics: it's an easily noticeable trend, I'm not asking you to find face of Jesus in the output numbers. As a programmer, none of these should be hard to understand, and I never said anything about greatly reducing errors: you can only avoid greatly <i>increasing</i> it, but that's natural requirement for anyone doing numerical work. --[[User:Ledrug|Ledrug]] 17:02, 2 July 2011 (UTC)
:: Making it numerically stable, that's challenging. It's easy enough if you have a small number of values of all about the same scale, but that's not always the case. –[[User:Dkf|Donal Fellows]] 17:11, 2 July 2011 (UTC)
