- If the population is normal, then the theorem holds true even for samples smaller than 30. In fact, this also holds true even if the population is binomial, provided that min (np, n (1-p))> 5, where n is the sample size and p is the probability of success in the population.

2022年7月6日 · The central limit theorem states that if you take sufficiently large samples from a population, the samples’ means will be normally distributed, even if the population isn’t normally distributed. Example: Central limit theorem. A population follows a Poisson distribution (left image).
2021年5月27日 · The central limit theorem says that in the limit as n n approaches infinity, the sampling distribution of the sample mean converges in distribution to a normal. As to your titular question, there is no threshold as to when the central limit theorem does or does not apply.
2016年7月24日 · The central limit theorem states that if you have a population with mean μ and standard deviation σ and take sufficiently large random samples from the population with replacement, then the distribution of the sample means will be approximately normally distributed.
2018年10月29日 · The central limit theorem in statistics states that, given a sufficiently large sample size, the sampling distribution of the mean for a variable will approximate a normal distribution regardless of that variable’s distribution in the population.
棣莫佛-拉普拉斯定理（De Moivre–Laplace theorem）是中央极限定理的最初版本，讨论了服从二项分布的随机变量序列。它指出，参数为n, p的二项分布以np为均值、np(1-p) 为方差的正态分布为极限。
2024年8月8日 · The central limit theorem for sample means says that if you keep drawing larger and larger samples (such as rolling one, two, five, and finally, ten dice) and calculating their means, the sample means form their own normal distribution (the sampling distribution). The normal distribution has the same mean as the original distribution and a ...
In probability theory, the central limit theorem (CLT) states that, under appropriate conditions, the distribution of a normalized version of the sample mean converges to a standard normal distribution. This holds even if the original variables themselves are not normally distributed.
