Applying ANOVA and Nonparametric Tests Simulation

Complete the simulation Applying ANOVA and Nonparametric Tests located on . Prepare a 350-700-word summary addressing the following items:

What are three lessons you learned relative ANOVA and Nonparametric tests?

As a result of using this simulation, what concepts and analytic tools will you be able to use in your workplace (i.e., how do you expect to apply what you learned)?

Based on your experience, what additional information would you recommend to the key decision maker in the simulation to solve the challenge given?

Learning Team Nonparametric Hypothesis Testing Paper

Using the same research question and data from the Learning Team Meeting Two assignment, conduct the equivalent, nonparametric test of hypothesis using the 5-step process.

Prepare a 1,050-1,750-word paper describing the results of the nonparametric hypothesis test. Be sure to include the following in your paper:

Formulate a hypothesis statement regarding your research issue.

Perform the five-step hypothesis test on the data.

Explain which nonparametric test you used to analyze your data and why you chose that test.

Interpret the results of your test, and explain the differences, if any, that you observe from your Week Three paper.

Be sure to include your raw data tables and the results of your computations in your paper, using both graphical and tabular methods of displaying data and results.

Individual Assignment: Quiz

Prepare to take a quiz on topics covered in previous weeks.

Discussion Questions

Can the formal hypothesis testing approach be used for nonparametric tests? How are parametric and nonparametric statistics different? How are parametric and nonparametric statistics similar?

Under what circumstances should a nonparametric test be used? Explain. What are the strengths and weaknesses of nonparametric tests? Can the outcomes of nonparametric tests be generalized to populations?

Why do you use the chi-square statistic? What type of data is used with chi square analysis? What are the nonparametric tests that correspond to each type of parametric test in Week 1 and Week 2?

What are some business situation in which ANOVA would be more appropriate than a (Z) or (t) test?

What are business problems in which the application of Chi ? Square statistic is appropriate?

How can bias affect business decision? Provide an example.
