OK now ....I am a Dowser..I am going to take one of those Scentific Double-Blind Test. There will be one coin placed under one of 10 cups. I will make my run and be scored. I will make a total of 10 runs. How many coins will I find?. Now you have to remember that all Dowsing is the same as guessing.The only question here is HOW MANY COINS WILL I FIND?
I thought it would be rather unique if we brought this thread around (full-circle) to where it was started. (Sure hope nobody minds.)
If, as you say, your dowsing is the same as guessing, then here is what you can expect to see for results.
Given 10 cups, 1 target in one of the 10 cups and you will execute the test 10 times (10 trials) then, here is what you can expect to see as results:
The Probability of Zero Hits is 0.348
The Probability of One Hit is 0.387
The Probability of Two Hits is 0.193
The Probability of Four Hits is 0.011
The Probability of Seven Hits is 8.748E-06
The Probability of Ten Hits is 1E-10
As you can see, roughly 93% of the time you will experience Zero, One or Two Hits.
Now, on the off chance that you were thinking of using this test as a tool to demonstrate how dowsing can do better than ordinary guessing, I would say you had better shoot for hitting at least 5 or more, to demonstrate a lot of confidence, maybe even 6 or more. That is, if you do the entire test, say 3 or 4 times (10 trials each), you could certainly boast some real talent if all those tests exhibited a score of 6 or more. (That's just my opinion, Carl or others might have a different mark that you should shoot for.) Of course it goes without saying, the test would have to be conducted and monitored according standard db protocol.)
BTW, have you actually done this test yet, and what were your results? You asked the question. Several have given you an answer, now it's probably time for you to do the test and tell us what happened.
Oh...... incidently, if you want to check my math, you can run the values through this and see for yourself:
P = C(n,k) pk (1-p)n-k
