1 CHAPTER 18 SECTION 2-3: MODEL BUILDING MULTIPLE CHOICE 76. In explaining the amount of money spent on children's clothes each month, which of the following independent variables is best represented with an indicator variable? a. Age b. Height c. Gender d. Weight ANS: C PTS: 1 REF: SECTION 18.2-18.3 77. In explaining students' test scores, which of the following independent variables would not best be represented with indicator variables? 78. In explaining starting salaries for graduates of accountancy programs, which of the following independent variables would not best be represented with dummy variables? 79. In explaining the income earned by college graduates, which of the following independent variables is best represented by a dummy variable? 80. If a nominal independent variable has 4 possible categories, the number of dummy variables needed to uniquely represent these categories is: a. 5. b. 4. c. 3. d. 2.

2 81. An indicator variable is a variable that can assume: 82. An indicator variable is also called: 83. In general, to represent a nominal independent variable that has m possible categories, we must create: 84. In regression analysis, indicator variables allow us to incorporate: a. interval variables into the model. b. nominal variables into the model. c. first-order variables into the model. d. None of these choices. ANS: B PTS: 1 REF: SECTION 18.2-18.3 85. If a nominal independent variable contains 5 categories, the number of dummy variables needed to uniquely represent these categories is: 86. Suppose that we want to model the randomized block design of the analysis of variance with, say, one nominal variable with three categories and one nominal variable with four categories. We would create:

    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.
