Line 263: Would anyone object to a note pointing out that the pseudocode can be run verbatim in a Python intepreter, but that in Python < 3.0 you'll need a <source lang="python">from __future__ import division</source> statement. (Can you tell I just got caught out by this? :D) [[User:Alexsdutton\|Alexsdutton]] ([[User talk:Alexsdutton\|talk]]) 15:05, 23 December 2010 (UTC) ::I think it would be inappropriate. The whole idea of pseudocode is that it's not language specific. -- [[User:RoySmith\|RoySmith]] [[User Talk:RoySmith\|(talk)]] 18:52, 25 December 2010 (UTC) == Divide by n vs n-1? == Can somebody explain why there are two different flavors of the formula for variance, one where you divide by n, the other where you divide by n-1? Obviously, for large values of n, they approach each other, but why the difference at all? -- [[User:RoySmith\|RoySmith]] [[User Talk:RoySmith\|(talk)]] 18:55, 25 December 2010 (UTC)
