Standard Deviations

When the RetroPsychoKinesis experiment ends, it will give you a final score. There are several numbers shown; the "standard deviations" is what you want to look at. Here are some possible scores and what they mean.

Score	Meaning
0.00	Random chance. You're not doing anything.
0.80	Hmm. You might be onto something. Keep trying!
1.28	Neat! Only a 10% chance that your results are coincidence...
1.64	Great job! Only a 5% chance it's coincidence... (Nearly proven!)
2.32	Wow! Only a 1% chance of coincidence... (Probably proven!)
3.09	Incredible! Only a 0.1% chance of coincidence. (Most definitely proof!)
3.72	Outstanding! Only a 0.01% chance of coincidence! (Most definitely proof!)

Details

These numbers are a measure of how much chance there is that your results are due to coincidence versus psychokinesis. It can also be called a z-score.

Most scientific areas consider the 5% level to be proof that something is happening. Parapsychology has restricted it to 1% to be very sure. Thus, if you get a total z-score of 1.64 or above, you're are almost certainly affecting it. If you are above 2.32 your results are quite impressive. It's to your advantage to do a lot of experiments, because then the small effects you have add up and are easier to see. It's also more scientifically impressive to have a lot of high scores instead of just one here or there.

The number might have a minus sign (-) in front of it. That means it went the opposite direction from what you intended. Still, a large number is meaningful.

The most meaningful score is your total z-score over many experiments. Enter the same email address for many attempts. Then have it show you your results. At the very bottom will be a total z-score. That is the best to judge against because it takes all your tries into account.
