Chapter 13 – Study Notes

 

1. ________________ tests do not require assumptions about the nature or shape of the populations involved.  Sometimes these tests are often called _________________ tests.
2. What are the advantages of nonparametric methods?
3. What are the disadvantages of nonparametric methods?
4. The ___________ of a nonparametric test compares the sample size needed to achieve the same results as a parametric test. This assumes that the sample meets the requirements for the parametric test. In the situation where the sample does not meet the parametric requirements, then the efficiency of the nonparametric test will be greater. Essentially, this means that it is best to use a parametric test when the data allows its use and a nonparametric test in situations where it is indicated.
5. Data are _______ when they are arranged according to some criterion.
6. A ____ is a number assigned to an individual sample item according to its order in the sorted list.
7. How are ties handled when ranking data?
8. Where can the SIGN TEST be used? What are the assumptions?
9. The explanation at the bottom of page 687 and the flowchart on page 688 will help the student understand the sign test procedure.
10. The sign test can be used to analyze ________ pairs.
11. ___________ data consist of names, labels or categories only.
12. The sign test can also be used to analyze claims about the ______ of a single population.
13. The STATDISK procedures are given on page 694.

 

Do the odd problems on pages 695-7.

 

14. The __________________________ test is a nonparametric test that uses ranks of sample data consisting of matched pairs. What assumptions are associated with this test?
15. The example on pages 699-701 demonstrates calculation of this test.
16. The STATDISK procedures are given on page 701.

 

Do the odd problems on pages 702-3.

 

17. The ________________________________ test is a nonparametric test that can be applied to two independent sets of sample data.
18. Another name for this test is ________________________.
19. What are the assumptions for this test?
20. Data that is in order or ranks is called ____________.
21. The nonparametric equivalent of the t test and z test is _____________________
22. A couple of good examples are given on pages 705-707.

 

Do the odd problems on pages 707-10

23. The nonparametric equivalent of the ANOVA is ______________
24. What are the requirements of this test?
25. A couple of good examples are given on pages 713-715.
26. The STATDISK procedure is given on pages 715-6

 

Do the odd problems on pages 716-719.

 

27. The _________________________ is a nonparametric test that uses ranks of sample data consisting of matched pairs.
28. What are the assumptions of this test?
29. What are the advantages and disadvantages?
30. A flowchart and several examples are given on pages 721-725.
31. The STATDISK procedure is given on pages 725.

 

Do the odd problems on pages 726-729.

 

32. A ______ is a sequence of data having the same characteristic.
33. The __________ test uses the number of runs in a sequence of sample data to test for randomness in the order of the data.
34. What are the assumptions of this data?
35. Several examples including those for large samples are given on pages 732-5.
36. This test can also be used to test _____________ above or below a mean or median.
37. The procedure for using STATDISK is given on page 735

 

Do the odd problems on pages 736-738

 

Work through the Review and Cumulative Review Exercises on pages 741-745

 

Table 13-9 gives a good summary of nonparametric tests.

 

Students enrolled in Math 1442 need to analyze the variable of SEX on DATA SET 6 (page 785). Use an appropriate test (or tests) to determine if this data comes from a random sample of the population. Email an analysis of your findings to [email protected]. Be sure to include the tests used.

 

The Chapter 13 test will be available from _______ until ______. It consists of 8 questions and has a time limit of 15 minutes. You can use your textbook and notes as you take the test.

 

Also, from Chapter 14 – the flowchart on page 758 provides a good summary of the methods studied in this course and the material on pages 758-759 provide a good perspective on the course.
