  Law of large numbers - Uncyclopedia
The law of large numbers is a term in political theory first coined by Thomas Hobbes in his famous political text, Leviathan.
Hobbes used this term to describe the behavior of numbers in the state of nature; he argued that, left to themselves, without a general theory of mathematics to overawe them all, numbers would descend into a war of all against all where only the largest numbers survived.
The usual use in debate is along the political speech formula of "Your (war/policy) has (killed/injured/maimed/widowed/economically ruined) (large number) (people/soldiers/immigrants/minorities)" A notable opponent of the law of large numbers was Josef Stalin, stating that "the death of one man is a tragedy.

 Law of large numbers - Wikipedia, the free encyclopedia
The law of large numbers is a fundamental concept in statistics and probability that describes how the average of a randomly selected sample from a large population is likely to be close to the average of the whole population.
The phrase "law of large numbers" is also sometimes used in a less technical way to refer to the principle that the probability of any possible event (even an unlikely one) occurring at least once in a series increases with the number of events in the series.
A consequence of the weak law of large numbers is the asymptotic equipartition property.

 Hussman Funds - Weekly Market Comment: October 25, 2004 - Law of Large Numbers
The law of large numbers basically says that if you make repeated, independent draws from a given “population,” the average value of your sample will approach the true population average as the sample size becomes large.
That said, the law of large numbers suggests that short-term returns should eventually begin to average out toward the long-term average if all is well.
Notice that the law of large numbers requires the samples to be “independent.” Following a particular investment approach over numerous time periods would qualify those samples as being reasonably independent, for example.

 Law of Truly Large Numbers - Wikipedia, the free encyclopedia
Critics of this law claim deny its application to supernatural events on the basis that they are by definition "above nature".
This way, the law is still valid as an explanation for the occurrence of highly improbable or coincident events, implying that there is no super-natural cause to be suspected in those occurrences.
Any supposed "supernatural" events are then interpreted as a result of physical laws that we are currently unaware of or do not understand properly, so the Law of Truly Large Numbers should apply to them as well.

 The Law of Large Numbers by Dr. Gary Goodman
The law states, that "In any chance event, when the event happens repeatedly, the actual results will tend to be the calculated, or planned, results." In essence, this means that repeated actions, over time, will, almost without exception, produce the results we seek.
While the law of large numbers has been applied to fields such as math and science for several decades, its power has just recently begun to be applied to the fields of business and personal growth.
Today, people from all walks of life are using the law of large numbers to achieve their highest objectives, with great confidence and complete peace of mind.

 Law of Truly Large Numbers
The law of truly large numbers says that with a large enough sample many odd coincidences are likely to happen.
The number is actually likely to be larger, since we tend to dream about things that legitimately concern or worry us, and the data of dreams is usually vague or ambiguous, allowing a wide range of events to count as fulfilling our dreams.
Given the fact that there are billions of people and the possible number of meaningful coincidences is millions of billions, it is inevitable that many people will experience some very weird and uncanny coincidences every day.

Although the repetition of dangerous practices leads to the conclusion that there is a higher likelihood of having a negative ending, repetition of higher spiritual practices on the journey to enlightenment, increase the odds for leaps of consciousness.
For example, the average weight of 10 apples taken from a barrel of 100 apples is probably closer to the “real” average weight than the average weight of 3 apples taken from that same barrel.
In particular, it permits precise measurement of the likelihood that an estimate is close to the “right” number.

A common story is the one about having a dream or thought about the death of a friend or relative and then receiving a phone call five minutes later about the unexpected death of that very person.
I cannot always explain such specific incidents, but a principle of probability called the Law of Large Numbers shows that an event with a low probability of occurrence in a small number of trials has a high probability of occurrence in a large number of trials.
So the total number of events that happen to us is about thirty thousand per day, or about a million per month.

The first 400 rolls (or even the first 1,000,000 rolls) are irrelevant for asymptotic results as their effect is wiped out by the zillions of rolls which are needed for the "long run".

But it becomes far too easy for anyone to dismiss anything by claiming bias, which disheartens me, as I just brought this up to a number of intelligent friends and they responded by saying 'but you can't be sure you've eliminated bias!' as though it was a mantra for avoiding statistical results they dont' like.

The question of whether an 11-judge en banc panel can adequately represent the opinions of a court with 28 judgeships (it currently has 24 active judges) has frequently come up in the debate over whether to split the 9th Circuit.
Arthur Hellman, a professor at the University of Pittsburgh School of Law and an expert on the 9th Circuit who has studied the en banc question, said there was no need to increase the size of the panel "based on what's called game-theory results, statistical results."
In 2000, Hellman conducted a study of whether the 11-judge panel was adequate.

Simply stated, the law of large numbers states that if you repeat a random experiment, such as tossing a coin or rolling a die, many, many, many times, your outcomes should on average be equal to the theoretical average.
By the law of large numbers, if you toss the coin many times, say 100, you should expect to get about the same number of heads and tails.

We must, instead, employ the ``Law of Large Numbers'' above the device level in order to obtain predictable behavior from atomic-scale phenomena which are statistical in nature.
At the same time, the ``Law of Large Numbers'' can also help us by providing statistical differentiation at scales smaller than those we can pattern directly or economically using lithography.
In this chapter, we examine various applications of the ``Law of Large Numbers'' above the device level to build reliable and controllable systems from nanoscale devices and processes that only have statistically predictable behavior.

The Law of Large Numbers says that in repeated, independent trials with the same probability p of success in each trial, the percentage of successes is increasingly likely to be close to the chance of success as the number of trials increases.
More precisely, the chance that the percentage of successes differs from the probability p by more than a fixed positive amount, e > 0, converges to zero as the number of trials n goes to infinity, for every number e > 0.
Note that in contrast to the difference between the percentage of successes and the probability of success, the difference between the number of successes and the expected number of successes, n×p, tends to grow as n grows.
