Sampling Distributions
The distribution of a statistic calculated from all possible samples of the same size drawn from a population is known as a sampling distribution for that statistic. In these lessons, students investigate the mean and standard deviation of sampling distributions of sample means and related concepts such as why the sample standard deviation is calculated by dividing by n-1 and the n < 10%N rule. Students will simulate sampling distributions and investigate the difference between a t and a z distribution.
