Goals:
- Recognizing how to answer an empirical question using regression
- Using SPSS to generate regressions
- Appropriately interpreting regression output
For this lab exercise, you will be using "Intro IO student scales only.sav" for all analyses. This is data gathered from an I/O class I taught a few years ago. Students completed a Big 5 personality survey, a job satisfaction questionnaire, and a teaching evaluation. Here is the information you need about the data set.
- At the beginning of the semester, I offer a personality test. Later in the semester, I provide students with a survey asking questions about my performance that they have observed, and questions about my performance that they have not observed. I suspect that students who are highly agreeable are likely to rate me higher on aspects of my performance they have not observed. Meanwhile, people who are low in agreeableness will rate me lower on unobserved performance. Thus, I want to learn whether I can predict how someone is going to respond on these unobserved performance questions using their agreeableness scores.
- Is there support for my hypothesis? (2 points)
- How well does my regression model fit my data? (1 point)
- If I have a student who scores a $2.5$ on the agreeableness measure, what is s/he likely to rate me on a performance scale where s/he has not observed my performance? (1 point)
2. Being a highly unethical person, I decide that in order to increase my teaching evaluations next semester, I will try to butter up any student who I think will give me a poor rating. I hypothesize that students who are highly conscientious will tend to rate me lower on observed performance (my lack of organization probably really annoys them!)
- Is there support for my hypothesis? (1 point)
3. I want to have a better understanding of what influences someone's general job satisfaction. One big question I have is what facets of job satisfaction (for example, satisfaction with pay) influence someone's overall job satisfaction.
- Which facet appears to be the most important (i.e. strongest) influence on general job satisfaction? (1 point)
- In addition to this facet, what other facets significantly influence my general satisfaction? (1 point)
- Using a backward method in determining which predictors to include, what does SPSS suggest about the best predictive model for this data? (In other words, what variables does SPSS conclude are important in this relationship?) (1 point)
4. I think that students who are less happy about my teaching will probably choose to complete their survey online rather than on paper.
- Do performance ratings predict what type of survey a student will choose? According to your analysis, how much variance does this model explain, and what does this indicate about the fit of the model? ( 2 points)
