Before you get started with this assignment, please complete the Research Hierarchy Activity to provide context for the assignment. Now that you have completed the Research Hierarchy activity, you can see how each type of research fits in a particular hierarchy. This is important because it provides information about each type of research study: its validity, rigor, soundness, reliability, and so on. With this context in mind, you will now examine the twenty articles provided here to give you practice in determining which article goes with each level of research hierarchy.
