They are called the strong law of large numbers and the weak law of large numbers. [ 16 ] [ 1 ] Stated for the case where X 1 , X 2 , ... is an infinite sequence of independent and identically distributed (i.i.d.) Lebesgue integrable random variables with expected value E( X 1 ) = E( X 2 ) = ... = μ , both versions of the law state that the ...

Observation that in many real-life datasets, the leading digit is likely to be small For the unrelated adage, see Benford's law of controversy. The distribution of first digits, according to Benford's law. Each bar represents a digit, and the height of the bar is the percentage of ...
Law of large numbers; Law of truly large numbers; Central limit theorem; Regression toward the mean; Examples of "laws" with a weaker foundation include: Safety in numbers; Benford's law; Examples of "laws" which are more general observations than having a theoretical background: Rank–size distribution
The law of truly large numbers (a statistical adage), attributed to Persi Diaconis and Frederick Mosteller, states that with a large enough number of independent samples, any highly implausible (i.e. unlikely in any single sample, but with constant probability strictly greater than 0 in any sample) result is likely to be observed. [1]
It is an umbrella term that covers the law of large numbers, all central limit theorems and ergodic theorems. If one throws a dice once, it is difficult to predict the outcome, but if one repeats this experiment many times, one will see that the number of times each result occurs divided by the number of throws will eventually stabilize towards ...
For example, it can be used to prove the weak law of large numbers. Its practical usage is similar to the 68–95–99.7 rule , which applies only to normal distributions . Chebyshev's inequality is more general, stating that a minimum of just 75% of values must lie within two standard deviations of the mean and 88.89% within three standard ...

Large numbers, far beyond those encountered in everyday life—such as simple counting or financial transactions—play a crucial role in various domains.These expansive quantities appear prominently in mathematics, cosmology, cryptography, and statistical mechanics.
