Discussion of The Chebyshev inequality
Abstract: Chebyshev inequality is an important method in Statistics. It is applied widely. This article first introduces the Chebyshev inequality, and gives the proof. Then using Chebyshev inequality proved Chebyshev law of large Numbers. Finally introduces the Chebyshev inequality in perfecting the law of large Numbers, solving and proving the inequality, and the application of the three aspects such as probability estimates. Therefore, chebyshev inequality has a certain theoretical significance and practical value. It further explores the application of Chebyshev inequality. This paper help readers to understand the application of Chebyshev inequality in real life.
