Don't they hire contract writers? So the writers aren't necessarily the view of vgchartz. But obviously that makes the site look stupid.
Again I could care less what sold more, they both sold a ton.
but when vgchartz margin for error in sales is way more than 1%. having articles stating something has passed another while still in that margin of error is just bad analysis which is bad because this site is supposed to be a sales analysis site. Not knowing how to correctly analyze data is a problem.
The same can be applied in reverse. If the two number get within the margin of error it's incorrect to declare either of them higher, atleast without noting the margin for error. Obviously statements by sony, or nintendo can produce more exact estimates.
To be fair to vgchartz, a lot of mainstream outlets fail to use statistics correctly with elections etc, However vgchartz is supposed to be a statistics website. So you'd think they'd use basic statistics correctly. http://www.robertniles.com/stats/margin.shtml
However the data suggesting they haven't tracked things and the fact that they're using data to a precision of 0.006% to declare something is silly when everyone knows VGC isn't that precise. Personally I think the DS will pass the PS2, and I think that's great. So I'm not trying to take anything away from the DS.
But again, I think vgchartz credibility isn't very high anyways. They are best used as a gist of sales mechanism.
