Sampling distribution of sample means (, ) (, ) (, ) (, ) (, ) (, ) (, ) (, ) (, ) (, ) (, ) (, ) (, ) (, ) (, ) (, ) The sampling distribution: each sample is unique, so there will be variation in the sample means. Nevertheless, sample means near the population mean are common, whereas samples means that are far away are rare. While the means of both the population and the sampling distributions are the same, the range of the sampling distribution is much smaller than the range of the population.
