Sampling distribution of a sample statistic
WebMay 12, 2024 · The central limit theorem states: Theorem 6.2. 1. For samples of a single size n, drawn from a population with a given mean μ and variance σ 2, the sampling distribution of sample means will have a mean μ X ¯ = μ and variance σ X 2 = σ 2 n. This distribution will approach normality as n increases. From this, we are able to find the ... The sampling distribution of a statistic is the distribution of that statistic, considered as a random variable, when derived from a random sample of size . It may be considered as the distribution of the statistic for all possible samples from the same population of a given sample size. The sampling distribution depends on the underlying distribution of the population, the statistic being considered, the sampling procedure employed, and the sample size used. There is often conside…
