WebAs the sample size increases, the distribution of scores will become more normal regardless of the population variance. This is known as the central limit theorem, which states that as the sample size increases, the distribution of sample means will approach a normal distribution, even if the population distribution is not normal. Web23 de abr. de 2024 · The variance of the sampling distribution of the mean is computed as follows: (9.5.2) σ M 2 = σ 2 N.
