This edition: Choosing Inference Procedures
This lesson is a review of what you have learned so far in the course. You have learned about proper study design, the types of variables under study, and the data studies generate. You have learned about inference and tests of significance, and that there are specific formulas to be used with certain types of data. You have also learned the basic assumptions behind these formulas. But when faced with several study designs, and different ways of collecting and reporting data, how do you know which test to use? This lesson describes a step-by-step method one can use to determine the type of statistical test needed to interpret a data set.
