Web28 jul. 2024 · Law of Large Numbers. The law of large numbers says that if you take samples of larger and larger size from any population, then the mean of the sampling distribution, \(\mu_{\overline x}\) tends to get closer and closer to the true population mean, \(\mu\). From the Central Limit Theorem, we know that as \(n\) gets larger and larger, … WebAnd that the strong law of large numbers states [informally] that P ( lim n → ∞ X ¯ n = μ) = 1 In the event the expectation E [ X i] exists, then E [ X i] = μ.
