[QUOTE="WilliamRLBaker"][QUOTE="blue_hazy_basic"][QUOTE="WilliamRLBaker"][QUOTE="SER69"] "According to the independent NPD Group, which tracks software sales in the United States, more than 33 million units of third-party Wii software sold in its first 20 months, compared with about 29 million units for Xbox 360 and about 20 million units for PS3 sold during each of their first 20 months on the market. NPD's tally of third-party software sales 20 months after each console's launch is the only way to make a direct, apples-to-apples comparison of the numbers. Wii remains the best-selling console of this generation" - Nintendo statement

and npd does not use data from some of the biggest stores in america.
NPD is very close though. You're talking fractions, they have a massive sample size.close? how is that? we only have npd data to use there is no comparison such as official comparisons...ect most of the time not every company releases detailed sales info on their product. Npd does not collect data from meijer, wal-mart, kmart...ect and these account for something like 30-40% of all game sales being the biggest stores in the world and often times wal-mart is the ONLY store in alot of places, no gamestop, no radioshack and no bestbuy or circuit city.
OK if you want an equivalent example. Polls for gallop usually have a size of approx 1000 people out of 300 million and have an accuracy of +/-5%. If NPD according to your estimation leaves out at worst 40% that is a sample size of 60%.Don't bother explaining basic statistics to someone who lacks any kind of mathematical aptitude. He's either too young to have studied it, or he's just the kind of person that doesn't have a grasp of math beyond the basics. Either way, it's futile.
