# Overall Summary

Total control runs: | 149741 |

Total tries: | 153334784 |

Total hits: | 76665522 |

Overall z: | 0.3020 | standard deviations |

Since each experiment involves 1024 bits, the total number of
“Tries” in the next line is 149741×1024, or
153334784. Examination of the bit sequences shows that 76665522 of
the total of 153334784 bits were ones. There were, then, 1870 fewer one
bits among a total of 153334784 than the most probable chance
expectation. This is equivalent to changing one zero bit in every
81997 bits to a one. The measured bias amounts to 0.3020 standard
deviations.

# Hit Histogram

The following chart summarises the results of all control run
experiments since control runs were begun on December 26, 1997.

The blue curve gives the
normal distribution for a large number of trials of 1024 events with
probability 0.5. (For a number of trials as large as 1024, the
binomial and normal distributions are equal on the scale of this
plot.) The red boxes show the actual number of experimental runs which
resulted in the given number of one bits in the 1024 bit stream
generated for each control run.

# Cumulative Deviation from Expectation

Any experiment involving a random data source can be
expected to, in the absence of perturbing influences,
follow a random walk around the most probable
value. As the number of experiments increases, overall
divergences should decrease.
When examining the results of
such experiments, it's important to satisfy
yourself that any non-chance effect you observe doesn't
result from the experimenter choosing to show you
results at a peak or trough of a series which is
swinging to both sides of the chance expectation
with a mean value equal to chance. The following is a
*deviation plot* of the all 149741 RPKP control runs
to date; it shows the absolute divergence of the experimental
results in the direction of bias preselected by the
subject compared to that expected by chance, and the
divergence in terms of standard deviations for the cumulative number
of trials for a probability of 0.5
on each trial.
