Identify the research hypothesis
This task focuses on identifying the research hypothesis for the power analysis. Clearly defined research hypothesis helps in determining the necessary statistical tests and guides the entire analysis process. The desired result is a clear and concise statement of the research hypothesis. Use your expertise and creativity to craft an effective research hypothesis. What are the potential challenges in defining a research hypothesis? How can you overcome them? Are there any resources or tools you need?
Determine the appropriate statistical test
Determining the appropriate statistical test is crucial for accurate power analysis. In this task, you need to consider the nature of your data, variables involved, and the research question. What statistical test would best suit your research question? How will you justify your choice? Are there any alternative tests to consider? Make sure to clearly explain the rationale behind your chosen statistical test.
