Why everyone is trying to say XBOX and PS3 is a statistical tie.??? i mean 50k is not that much meager either.. its 1.5 million dollar sales for PS3. :$ and we can also say maybe PS3 had 100k lead and NPD is showing it less.. it should be taken as +/-25k for each console instead of only +25k for XBOX and -25k for PS3 to make it a tie. :$..
i think XBOX has even won by 900 units.. it was something like 287.1k and 288k.. So it was a win for XBOX so this is a win for PS3 |
No... that would also be a statistical tie. They would both be statistical ties.

Winning is winning.
Or is there a rule now on how many sales it takes for it to automatically be a "statistical tie"?
|
Yes. There is a rule on that.
It's called the margin of error.
It's a statistical rule... for statistics. Which these numbers are.
It's universal...
For it to not automatically be a statistical tie the two numbers have to be far enough apart from each other to not be within each others "margins of error."

We don't know the NPD margin of error though...
Or do we?
