Question
Mike is interested in assessing whether there is a difference in how much college students argue with male versus female professors regarding an exam grade. Mike obtains the permission of 20 men and 20 women professors to observe their classes the day they return graded midterm exams. In each class, Mike records the proportion of students who complain about some aspect of the midterm and how it was graded.
1) The variables described in each scenario.
2) The number of IVs and DVs described in each scenario.
3) The nature of the independent and dependent variables described in each scenario, e.g. categorical, quantitative, etc.
4) The measurement system used for each of the variables (IVs and/or DVs) described in each scenario, e.g., nominal, ordinal, interval, or ratio.
5) Select the test statistic that is appropriate for the hypothesis described in each scenario; describe which guide (from the two selection guides in the back of Chapter 2) you used; and your rationale for the selection of the test you did choose.
Explanation / Answer
1.) The variables are exam grades and and students
2.) Independent variable : Students
Dependent variable : Grades
3.) Natureof independent variable is categorical and dependent variable is quantitative
4.) Themeasurement system used to describe the dependent variable is ordinal.
5.) t-test would be appropriate as we want to compare the mean grades for the male and female professors.
