Cool! I'm impressed!

Like I said, I don't know the mathematical basis for determining what one would expect by chance. In my previous post, I pulled some numbers out of the air, but I don't know if they were the right ones to go by.

Anyone know anything about statistics and random sampling? Out of 30 random runs, is a 21-9 ratio (slightly better than 1/3) significant or not?

More importantly, though: How do you feel about the isolator now? After listening carefully to the same track 30 times in a row, and after 9 incorrect guesses (split evenly between the two possible guesses), do you still think there's a difference?

Oh, and out of curiosity, how long did it take you to go through it all?
