Description
A table to help students decide which method or methods are appropriate to answer questions about sampling distributions.
The questions are:
1.) What is the shape of the original distribution? (Normal or non-Normal)
2.) What is the sample size? (small or large)
3.) Is the population standard deviation known? (yes or no)
4.) Do you have a modern graphing calculator or computer? (Some older textbooks assume that students do not have access to one of these, and thus have different criteria for choosing between a "z" or a "t" model of the sampling distribution than online resources/practice problems do, causing a lot of confusion.)
