Quantitative Methods Homework -

You will find a data file cryptically named "mediation.sav" which is what you'll be working with for this assignment. In this database, you will find three variables: predictor, mediator, outcome. The predictor is the first variable, the ... you know what, I think it's pretty self explanatory.

The first part of the assignment is for you to name the variables. You could name them something related to your scientific field of study. Which would of course be boring, but acceptable. Alternatively, you could come up with something funny. This would be far more interesting. The purpose of the assignment is to demonstrate that you can conduct these analyses and interpret them correctly, and the data are fictional, so feel free to have some fun.

Using the procedures taught in class, please do the following:

1) Manually go through the Baron & Kenny (1986) four steps. Note what you would conclude if you used this method.

2) Next, test the potential for mediation using the Sobel test. I want you to test the two necessary regressions manually, and point out to me which numbers from your output are the values of interest. This is important: you need to demonstrate that you know which numbers you are supposed to be pulling out of the output. From here, it's easiest to just use the Sobel online tool that you'll find in my handout regarding how to test mediation.

3) Then, using the indirect.sps file that we used in class, conduct a bootstrapping test of the mediated effect. See my handout if you get stuck with this.

4) Next, compute the percentage of the direct effect that is mediated, using the equation provided in my slides.

5) Finally, provide a write-up of your findings & provide your SPSS output.

Note - Need expert in statistics to work on this homework, need SPSS, calculation and report output.
