Survey research

1) You are hired by a survey research firm to do research on the topic of job satisfaction. a. What’s your conceptual definition of “job satisfaction” (use your own words to define this topic)? b. Using your conceptual definition as a reference, design 5 effective closed-ended items assessing the topic. Assume that they will be answered on the following rating scale: 0……….1……….2……….3……….4……….5……….6 Not at All Very Much c. Using your conceptual definition as a reference, design 3 effective open-ended items assessing the topic. 2) You are given the task of investigating people’s liking for decaffeinated coffee vs. caffeinated coffee. a. You decide to do a two independent groups experiment to explore how much people like each type of coffee. i. What will you be manipulating in this study (i.e., what’s your independent variable?) ii. What will you be measuring in this study (i.e., what’s the dependent variable)? iii. How would you go about assigning participants to conditions in your study? iv. Identify and describe two ways that you would go about controlling extraneous variables in this experiment (be sure these different from your answer to question iii above). v. What statistical test would you use to analyze your data (assume that you have numerical ratings for how much each type of coffee was liked)? b. You decide to do a repeated measures experiment to determine which type of coffee people prefer. First, you give each participant a 4 oz cup of decaffeinated coffee, ask them how much they like it, then give each participant a 4 oz cup of caffeinated coffee, and then ask them how much they like it. i. Identify and fully describe the major problem with using the above procedure in a repeated measures design. ii. What is one thing you could do to improve on this design? How would you do it? 3) If researchers were investigating the variables that affect helping behavior, would they be more likely to use a straightforward manipulation or a staged manipulation? Why? 4) Two researchers conducted an experiment on willingness to be a kidney donor among college students. The researchers had participants read a passage about a person (unrelated to the participant) who was in need of a kidney. The researchers manipulated the following information about the person in the passage: whether the person was younger (age 25) or older (age 55) and whether the person regularly drank alcohol or did not drink alcohol. After reading one of the passages, participants rated their willingness to donate a kidney to the person on a 0 (Not at All) to 6 (Very Much) scale. a. What is the design of this experiment (be as specific as possible)? b. How many conditions are there in this experiment? c. Identify the independent variable(s) and the dependent variable. d. The researchers obtain the following means for willingness to donate: younger/drank alcohol = 1.40; younger/did not drink alcohol = 3.50; older/drank alcohol = 1.10; older/did not drink alcohol = 1.30. Assume that there are equal numbers of participants in each condition and that mean differences greater than 1.00 are significant. i. What are the marginal means? ii. Describe the nature of the main effects [i.e., Are there significant main effects? If so, which variable(s) show a main effect, and what is higher than what? If not, which variable(s) show no difference?] iii. Graph the within cell means (you can hand draw it). Be sure to label all relevant elements of your graph. iv. Is there a significant interaction? 1. If there is a significant interaction, describe all aspects of that interaction (i.e., the nature of the interaction) in a brief paragraph.
