Conclusion:
After concluding the experiment, I noticed that the Gaussian curve is a good
approximation of the probability of large marbles going in a slot. Although, this is only
true when you roll a large amount of marbles. The more marbles you roll, the closer you
will be to approaching an average x of zero. After writing a hypothesis, I started rolling
the steel balls and noting down the results. By doing this, I noticed that my hypothesis
was not exactly accurate. I incorrectly predicted that the distribution and standard
deviation would stay the same for the steel marbles and the large marbles. The steel
marbles seemed to give a much wider spread which didn’t quite resemble the Gaussian
distribution. The steel marbles were somewhat erratic as they landed more in some
random bins such as negative 6. This may be because the marbles move faster, hit more
nails, and spread out more. This can be shown by the increase in the standard deviation
when we moved from the large marbles to the steel marbles. It was also interesting to
