This tutorial is designed to help you develop a framework for choosing the correct statistic to test your hypothesis. The tutorial begins with a set of questions you should ask when selecting your test. It is followed by demonstrations of the factors that are important to consider when choosing your statistic. Once you understand how to choose among statistics, you should test your knowledge by doing the practice exercises.
This tutorial assumes that you know all of the basic univariate statistics. The tutorial is not designed to teach you the formulas and procedures for conducting these tests. Rather, it focuses on how to select the appropriate statistic to test a particular hypothesis.
Students enrolled in PSYC230 - Elementary Statistics - who wish to receive extra credit for doing the tutorial should take the quiz posted on the Blackboard at Emory class site.
