Screening data prior to applying specific statistical analyses is a critical requirement during a research project. The dissertation is no different. In fact, the methods chapter (chapter 3) of your dissertation proposal should be a step-by-step plan that addresses the data screening that will be performed and how the data will be evaluated to make sure that the planned statistical tests are appropriate given the data obtained. This assignment will allow you to practice your understanding of these procedures so you will be able to write this section of the dissertation proposal.
