Forums - Gaming - VGChartz is as tracking service as good as NPD, or why npd gospel is retarded

Both extrapolate data based on a set of data points

It is not clear how many data points habe in th us But NPD has used 4500 inputs for the whole phone os representation Let me tell you that they wont use much more for the hardware and software data.. Npd gospel is based on familairity due to being the old establised order Which is not logical!

Maybe it’ll turn out that those who disagree with you actually have a solid grasp of the facts. There’s a slight possibility that, after all, you’re the one who’s wrong.

NPD has more data, thus is more accurate

Yes, it extrapolates, but it extrapolates based on more data

But most importantly, both are estimates with errors. Really the numbers here should have error measurements attached, but we can't get everything



When the big 3 will quote Vgchartz numbers in their press releases, like they are now quoting NPD and GFK numbers, I will treat Vgchartz equally.



So it is happening...PS4 preorder.

Greatness Awaits!

So VGChartzs is suddenly accurate and reliable? Give me a break just because they get tracking pretty close during the holidays isn't enough for me to suddenly switch gears and say they are up there with NPD.



They get more data. NPD simply have more funds/staff to go out there and get the data and thats why the numbers are generally regarded as "correct".

NPD numbers are still estimates, but they offer a better range of accuracy than VGChartz. VGC is growing slowly but surely... But for American numbers you arent gonna get more accurate than NPD anytime soon.

I take polls from NPD all the time. Never once have I taken one for VGC.



Don't question my god. I belive in NPD, nothing will shake my faith.
