Overview
An apparent phenomenon which defies-the .theory of probability occurs
-.when Subject 2 plays-this experimental game. We significantly exceeds his
prabability of success, .25, by scoring over .29. The question that. this
report addresses is: Is there a statistical. or logical reason why he did
so we71? The methodology used to attack this problem and the resulting
conclusions are summarized below. This summary can also .serve as an outline
to this detailed report.
I. .Statistical-Analysis of the Machine Experimental Data
Pre-experiment data analysis discovered a non-random characteristic
through the examination of forward-backward state transitions (i.e.,
Red-Blue,-Blue-Red). Wowever, the coefficient of correlation between
the forward and backward states of .58 for the experimental data, .49
for Machine 1 data and .48 for Machine 2 data were considered law
enough that this approach was dropped. Pre-experiment state transitions
had a coefficient of correlation of .93.
The experimental data randomness analysis consisted of examining
the distribution of color totals and the distribution of .each color
taken over various combinations and permutations of the data. No evidence
of non-randomness was discovered.
II. Rnaiysis of the Subjects' Data Responses
The subject's responses were analyzed with the emphasis on the
discovery of his strategy or the unveiling of a trend which would give
him a statistical advantage. .The possibilities investigated produces.
no solid reason how he was able to be so successful. Wowever, in one
case there is a strong indication w~ he was able to succeed, It appears
that he vas learning the states of Machine ?_. The details of this are in

the remainder of the report.
Miscellaneous
Thereport contains a section entitled "Miscellaneous" far the
purpose of displaying detailed data which wasn't directly required by
the above more general analysis. Details such as how many successful
choices in the color red during the 50th trial were there, or what was
the relationship of the number of passes to the number of successes.
The terminology used is as follows: the term "trial" refers. to the
string of machine states and corresponding choices from the time the
subject begins until he makes 25.non-passing choices. A sample.is a
machine -state and/or subject choice (including passes). There are
(25 + # passes/trial) samples-in each trial.

I. Statistical Analysis of the Machine Experimental Data.
Forward-backward State Transition Analysis
In a previous memorandum (Me~r~o ORD 2240-75, i2 June 1975 to
SG11
the question of randomisers with the. emphasis on state transitions as an indication
of non-randomness-was addressed. The data used in the investigation consisted
of pre-experiment trials, The purpose of this section is to do a similar.
investigation using the actual data which occurred during S2's experiment.
-Table 1 presents all possible transition frequencies. All transitions
should have equal probability.

The conclusion based on pre-experimental data was. that these state-pairs.
show a very strong relationship between forward-.and backward transition
frequencies-{coefficient of correlation =.93). However, computing the. coefficient
of correlation, ps2 actual data = .58, it becomes apparent that the
degree of dependence is slightly reduced. Therefore the dependence of
forward to backward states can no longer be considered as a strong indicator
of non-randomness. ,

The data used in the above discussion consisted of trials from both
machine 1 and. machine 2. Since non-randomness, made apparent by the state
transitions, clearly existed forpre-experimental data, the investigation of
the experimental data continued to include a search for this trend in the
individual machines.. The transi ions (including identity) are as follows:

Experimental Data Randomness Analysis
The machine data used during the S2 experiment his been combined, summarized
and/or permuted in
an attempt to establish evidence o,r randomness or non-
obvious indication
this task would be simplified because
of-non-randomness would have evol d !
v e ~~
,,
it-would have become a closed form i
problem (i.e.,-the solution would be - the data has non-random characteristics).
However, wha~has result d is ha .various forms of the data have bee_n__examined
with all ind_ica_ting that the data is random.
Tables,. plots and commentary are presented in this section to demonstrate
randomness. and in some cases just to provide general information concerning
the machines data.
.The distribution of the colors collectively and for each machine is
as follows:

Machine l was not-used in as many trials as machine 2 (44 trials to 56
for. machine 2), thus the difference in totals. The standard deviation of
binomial distribution with n=3483 and p=1/4 is 25.56-which would imply that
each separate number is reasonably close to the mean.
Accepting the distribution of the totals consider. the distribution of-the
colors throughout the experiment. The popluations used for this .investigation
consisted of the first 25 samples of each trial (100 trials total). This
population is acceptable since the distribution of its totals was reasonable
and since .the performance of S2 was approximately-the same. (success-29.61/)
for this subset,

The .following three approaches comprise the strategy used to attack
.the question of color distribution..
1. Each _tri_al._~abbreviated to 25 samples) as analyzed__separate interval.
Obviously this .will indicate .any bias. within each trial;,..
.The data (2500 samples) is divided into intervals of five samples
each. This will indicate unusual. repetitions either: within tie
interval or interval-by-.interval..
3. The data. is reformatted into 25 intervals of 100 samples,-.where the-
nth interval consists of the nth sample in each trial.
The results of approach l is shown. in Figures l.l.a, l.l.b, l.l.c, and.
1.l .d.~
The binomial distribution for this strategy (n=25 p=1/4) is mean. 6.25
and the variance 4.69. The plots indicate randomness thro~ac~hout the 700
trials,
The results of approach 2 are similar to approach 1 and are shown in
the four tables in Figure 1.2. The plots indicated randomness but are-not
shown because of monotomy. The binomia l distribution mean is-1.25 and the
variance .94.
The binomial distribution mean and variance for approach 3 is 25 and 18.75
respectively (Figure 1.3). A plot of the data (Figure 1.4) for the "RED"
case because of the concern for the higher variance and ranges. The 13th sample
seems to have an unusually high frequency of "RED" (44~). However in .general
this investigation has not produced a significant non-random characteristic.

Best Strate
Based. on the above analysis what is the best strategy to pursue? No
good strategy is available based on .the randomness of the data. The best
possible strategy based- on the above transition matrices is:
1. If the subject can't distinguish between machine then .press blue
- when blue appears, else pass.
2. If the subject-can distinguish them on Machine 1', press yellow
when. yellow occurs, and on Machine 2 press blue when red occurs.
For all its worth, of the existing data the following success would
result - 26%, 26%, and 27%.

Analysis of S2 Data Responses
The attempt here is to discover a reason for S2's success at responding.
The investigation was unable to give'a definitive reason for his success:
Although no strategies were uncovered there was in-one case a indication that
the subject was learning.
Two major approaches have been taken in this investigation. .They are.
as follows;
1. Strategy of S2 - Was there any trends in the way he guessed?
he respond based on the previous state of the machine?
2. Hit analysis - Did the subjects' hits (correct choices) increase
within a~run; did it increase from run to run (i.e., was he
learning?)
Strategy of S2
For general- information and future reference the first fig;~re (Figure 2.1)
presented i s the actual .choices,, One i tem_ of .curiosity from_ t_hi s i s that
wren h~passes, he tends to do_1_t in__s~i^.n,gs. This characteristic. of course
wasn't pursued because of its insignificance to .this report; however, observations
like that are pointed out throughout the report as possible importance to those
in the field.
Total Color Choices
The distribution of S2's color choice totals are shown below.-

As can be seen his results with blue are significantly lower than the others.
However, assuming the probability of success to be .25 and using- the binomial
distribution the expected value =69 and the standard deviation = 7. The
inference from this as .that the 60 81ue hits are not a statistical abnormality.
However, it is curious that he dial so much worse on his lowest preference.
State Transition Color Choice
This:investigation consists of examining the states of the machine verses.

does the subject consistently choose one color on the next turn). Consider

IV. Tables of state transitions which reflect the influence of the subject
on the machine: For color choices of the subject the table shows the number
of colors the machine has on the next sample. For example on the first table,
when the subject picked yellow, on the next sample 197 times-the machine
state was yellow.

V. Because of the possibility that the subject was learning the state of machine
2 the distribution of the colors are plotted in Figures 3.8, 3.9, 4.0, and
4.1. The only states used are those in which the subject didn't pass.
Therefore there is a total of 25 for each trial.
