Apologies I thought this was general knowledge, maybe I should have outlined it more in the OP. VGC: http://www.vgchartz.com/methodology.php NPD: NPD market research is based on responses from nationally representative samples. Our Research Science team’s extensive expertise in sampling and weighting techniques ensures return samples are demographically balanced to reflect the total population. VGC uses slightly different language to say the same thing - that is that the majority of their data set is retail and user-polled data that is extrapolated based on an understanding of the historical trends in market size. The reason that NPD is held to be more accurate is that it has a (substantially) larger sample size, meaning that using the same tecniques, they'll normally (but statistically, not always) arrive at more accurate 'guesses.' |
That is such a vague statement that I"m not sure how you equate it to being the exact same methodology that VGC uses. Sounds like you're making up a bunch of BS to make VGC's horrendous tracking look better. And yes it's horrendous. Defend it all you want but that doesn't stop the numbers from looking like a joke every month. NPD is taken as *fact* by some of the largest corporations in the world. If it's good enough for billion dollar corporations to base their entire market strategy around then I'm not sure why it's not good enough for you.
Sigs are dumb. And so are you!
