Module 2. Statistics Review for Psychological Measurement
If you have already taken a statistics class, you probably spent a good portion of the term on statistical significance testing, learning about t tests, analysis of variance, and other such statistical tests. If you dreaded that part of your statistics class, you are in luck because in applied psychological measurement we typically do little in the way of statistical significance testing. Instead, we tend to focus on either descriptive statistics or estimation. For those of you who have not had an introductory statistics class or who have but are in need of a refresher, an abbreviated review follows. However, please see the Further Readings listed at the end of this module for a more detailed discussion and explanation of the statistics discussed below.
