1 CHAPTER 19 SECTION 4: NONPARAMETRIC STATISTICS MULTIPLE CHOICE 111. The Friedman test applies to which situation? a. When the problem objective is to compare two or more populations. b. The data are either ordinal or interval but not nominal. c. The data are generated from a randomized block experiment. d. All of these choices are true. ANS: D PTS: 1 REF: SECTION 19.4 112. The nonparametric counterpart of the randomized block model of the analysis of variance is the: 113. A nonparametric method to compare two or more populations, when the samples are matched pairs and the data are either ordinal or interval but not normal, is the: 114. In a Friedman test for comparing three populations, provided that there are five blocks, the test statistic is calculated as F r = 6.594. Then, the most accurate statement that can be made about the p -value is: 115. The Friedman test is always: a. one-tail with > in the alternative hypothesis. b. one-tail with < in the alternative hypothesis. c. two-tail d. None of these choices. ANS: A PTS: 1 REF: SECTION 19.4

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
