Q1) Define what the chi square distribution is. Why do you use the chi-square statistic? What type of data is used with chi square analysis? What are some limitations of the distribution? What is the goodness of fit test?

Q2) 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?

Q3) What are some other non-parametric tests (3)? What role or purpose does each serve? What would be a comparative parametric test for each non-parametric test?

Q4) Another set of nonparametric methods deals with the analysis of ranked data. When and why would you utilize these various methods? How do these tests relate to the one that have been discussed previously in this class? Compare and contrast.

Q5) Under what circumstances a nonparametric test should be utilized? Explain.

What are the strengths and weaknesses of nonparametric tests? Can the outcomes of nonparametric tests be generalized to populations?
