Generalizing from a sample to a population that involves determining how far sample statistics are likely to vary from each other and from the population parameter.
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 .
The larger the sample size, the smaller the variance of the sampling distribution of the mean.
Given a population with a finite mean μ and a finite non-zero variance σ2, the sampling distribution of the mean approaches a normal distribution with a mean of μ and a variance of σ2/N as N, the sample size, increases.
