So in the end the total is 15/20? That's not bad - there's only about a 4% chance of that happening if you were guessing (by "that" I mean a result of 15 or more out of 20, or of 5 or less out of 20). The weakest test of stat. significance is usually taken to be 5%, so that actually qualifies. Are you sure you didn't throw any trials away? A common error is not to count some of the results that go against your expectation (that's called cherrypicking) - because you weren't quite ready, or the volume was too low, or something. Don't do that! It's also a little dangerous to combine two separate trials the way I did above - if we just keep 8/10, there's a 11% chance that happened randomly. -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=38258 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
