Nonparametric Tests

During this week you will work in the discussion area for the last time to identify a research question created in week 1 that would utilize any of the nonparametric tests (e.g., Chi-Square test of independence, Mann-Whitney U Test, etc.) listed in the Required Readings from Sukal (2013) for this week. If there are no research questions that fit these types of statistical analyses, you will need to decide on a new question before moving forward with the assignment.

In your initial posting for this assignment, include the following:

  • Identify an appropriate research question that would require the use of a nonparametric test to answer. Pick the question from the list created in Week 1 or identify a new question if there are no appropriate ones from Week 1.
  • Describe why this question is appropriate for the selected statistical test.
  • Identify the variables in this study and each of their attributes: discrete or continuous, quantitative or categorical, and scale of measurement (nominal, ordinal, interval, or ratio).
  • Do the variables fit the qualifications for the selected statistical test? Explain.
  • List the statistical notation and written explanation for the null and alternative hypotheses.
  • Describe the types of errors that could occur.
