So if I toss a coin twice, predicting heads both time, and it does actually happen to come down heads both times, that means there's a 75% certainty that I can see into the future?
Stop being childish Pixel42 - keep above the others or you will become like them. It means that you can predict with a certain accuracy that the coins will land on heads twice, not that you are precognitive.
With such a small sample, it can also be shown that it can happen by chance as well so would not be very relevant – i.e. 25% certainty that you cannot do as you claim. Getting 20 correct would show that you with high certainty correctly predicted the coin toss accurately or that you have a trick coin or that you are manipulating the test etc.
I will be aiming for a significant number of tests so that chance is reduced to virtually zero.
