Review Materials
These review materials are intended to provide a review of key statistical concepts and procedures. Specifically, the lesson reviews:
populations and parameters and how they differ from samples and statistics,
confidence intervals and their interpretation,
hypothesis testing procedures, including the critical value approach and the P-value approach,
chi-square analysis,
tests of proportion, and
power analysis.
For instance, with regards to hypothesis testing, some of you may have learned only one approach — some the P-value approach, and some the critical value approach. It is important that you understand both approaches. If the P-value approach is new to you, you might have to spend a little more time on this lesson than if not.
