The coin thing reminds me of that Statistics 101 question:
You toss a coin ten times and it comes up heads all ten times. Is the eleventh toss more likely to be:
1) A head.
2) A tail.
3) 50/50 chance of heads or tails.
(Answer Below)
-Neil
Answer: 1) A head.

Crashfrog re. coin: bullseye!
Part of the purpose of the example is to show how easy it is to let unsupported assumptions pass into statistical test design.

(Can you tell I was raised on Mad Magazines of the classic era? )
quote:
Mike: Predictions? If we perform an experiment N times, with a probability M of a particular outcome...
The point of the example vis-a-vis the current topic (the big bang), is: how do we determine M? There are two ways, theoretical and experiential (and combinations thereof).
M might be 1 (doubtful); or it might be 0 (like the ID folks presume); or it might be really, really close to 0. We may know the answer someday, or we may not. Physicists and cosomologists have a lot of heavy lifting to do. (But they're a bright bunch!)
