Chebyshev's law of large numbers
There are two different versions of the law of large numbers that are described below. They are called the strong law of large numbers and the weak law of large numbers. Stated for the case where X1, X2, ... is an infinite sequence of independent and identically distributed (i.i.d.) Lebesgue integrable random variables with expected value E(X1) = E(X2) = ... = µ, both versions of the law state that the sample average WebAccording to Chebyshev’s inequality, the probability that a value will be more than two standard deviations from the mean ( k = 2) cannot exceed 25 percent. Gauss’s bound is 11 percent, and the value for the normal distribution is just under 5 percent.
