PROBABILITY & STATISTICS of COIN TOSSES
Did our graph look like this? ANOTHER COIN TOSS EXPERIMENT Toss 10 coins Toss 1000 coins Toss 100 coins Looking at these results we would guess that these coins are badly biased – with an 80 probability of showing heads This is an example of the use of the statistics of very large trials to infer probabilities RANDOM WALKS in COIN TOSSING |
How many coin tosses per participant?
For a change of at least 10%, we calculated that 263 coin tosses per participant would be required to achieve 90% power to detect this difference with a significance level of 0.05. We performed a comparison of proportions.
Is coin tossing a random event?
Coin tossing becomes physics rather than a random event. It is the human element that makes the process random in that each toss tends to be at a different speed, sent to a different height, launched at a different angle or caught in a different manner.

More specifically, you want to know the probability of your test statistic, 549 tails out of 1000 coin tosses, occurring with a fair coin If that probability is sufficiently low (below your alpha level), you will reject the idea that the toss is fair and conclude that it is rigged |
