Chebyshev’s theorem 中文

WebAug 21, 2024 · The rule is often called Chebyshev's theorem, about the range of standard deviations around the mean, in statistics. The inequality has great utility because it can be applied to any probability distribution in which the mean and variance are defined. For example, it can be used to prove the weak law of large numbers. WebWe use Chebyshev's Theorem, or Chebyshev's Rule, to estimate the percent of values in a distribution within a number of standard deviations. That is, any distribution of any shape, whatsoever. That means, we can use Chebyshev's Rule on skewed right distributions, skewed left distributions, bimodal distributions, etc.
