Re:Mp3 is better than CD in some cases (Score 1)

What if it's a fact. Perhaps the encoding and compression of some music actually makes it "better" (remember that better in this case is defined as "less annoying for the majority of the population". Possible, but this test doesn't allow you to say that. Notice that none of the error bars clear the 0 line in the positive direction, while there are clearly those that do so in the negative direction. Yes, these are 95% confidence intervals, but keep in mind that n=16 after a selection process that threw out about the same amount of other listeners. So you can say that some codecs actually enhance audio, but this test doesn't back you up. (It doesn't convincingly refute you either, though. :)
