The Sample Planning Wizard automatically tailors its analysis to comply with the
constraints of your problem. It works with simple random samples, stratified
samples, and cluster samples. It works with small samples as well as large
samples. And it uses the t distribution, binomial distribution, or
hypergeometric distribution, when the normal distribution is not
appropriate.
