What value of X would you consider;
a) unusual

c) paranormal

b) depends on how you define remarkable
c) either +infinity or -infinity because mathematically extremely improbable events sometimes must happen somewhere at some time and the only way I can see how that could show 'paranormal' is if the number of times it happens is beyond 'improbable' because it is impossible so to give it zero probability and +infinity or -infinity number of times IS impossible (and complete nonsense, of course) or, in other words, has exactly zero probability of happening.

b) 10 - One chance on 1024, which is remarkable.
c) 40 - Slightly less than one chance in a trillion for this. Assuming, hypothetically, that all possible "cheats" have been ruled out (and also that the experiment was carried out just one time with one individual), I would consider the possibility of an extrasensory perception being present. However, the experiment would need to be replicable before considering theories.
If a billion people are playing this game once every day, then it is likely that within a year someone will correctly "predict" 40 consecutive coin tosses. So in this kind of scenario I would require something like X=80 to consider something potentially "paranormal."

Originally posted by SoothfastOk., where on that scale would you consider it proved beyond reasonable doubt that the coin is predictable? The question's assumes that either the coin is unpredictable or God exists, it strikes me that that is something of a false dichotomy - for example, has cheating been eliminated? So really the question is when is it proved that the coin is predictable (a run of 5 is already past 95% confidence) and what you've done to eliminate cheating.

Originally posted by DeepThoughtI do not see where a god necessarily figures into this inquiry, though a god could be neatly tucked into the "paranormal" category. But "paranormal" phenomena are tricky things: if one such phenomenon were to be proved to be real by means of the scientific method, then by definition the phenomenon is no longer paranormal.

I'll just say that if, in the course of a single experiment done once, someone were to correctly predict X=40 coin tosses in a row, and all possible cheats were eliminated (this is again quite hypothetical), then I would be prepared to entertain explanations that might currently be considered paranormal. If pressed, I would say perhaps information is being received by the test subject by some weird quantum mechanical means that amounts to something like precognition. I don't know. It's a "what if" scenario, and again, I would say the experiment would need to be replicable, otherwise it could indeed have just been a really, really, really lucky run of guesses.
How about X=500?
EDIT: Of course, an X=10 result received four times in a row is equivalent to an X=40 result, and could be considered successful replication of an experimental result. I hear that six-sigma certainty is good enough for particle physicists to consider a new particle as being "discovered." What X value does that correspond to in the current context? My statistics books are somewhat dusty and I just can't be bothered. 😉

Originally posted by SoothfastFrom memory it's one chance in half a billion, which is 1/2^29, so particle discovery claims happen at the same level of confidence as one would place on the prediction for the thirtieth toss made by someone who had correctly predicted the previous twenty nine tosses of a fair coin.
