The SPSS test will be a 2 way mixed ANOVA. The interaction will be significant, and you will need to run tests of simple main effects. It is scheduled for the last week of class in the testing center. When you arrive, you will be escorted to a computer and given a paper test and a thumb drive. The data you will analyze is on an excel file on that drive. There are three versions of the test; A, B, C. Make sure you open up the correct excel file (A, B, C). The intent is that you will copy and paste the data from the excel file into SPSS. Make sure you watch the video that explains how to do this. A printed summary of the instructions is here . The data that is on the excel file is also printed out in a table on page 1 of the test. If you want to, you can enter the data in by hand. Just be sure to triple check your numbers as data entry errors will likely lead to a failing grade.


This test is open notes/book. You can bring any printed materials you want, but you cannot use your phone or access the internet. Also note that you cannot print anything in the testing room. Make sure you make no errors transcribing numbers from the screen to the test paper. There is no time limit, but you should block off two hours to be safe.

What to expect

How to Prepare

The SPSS test very much resembles SPSS assignment 8. Make sure you review your feedback on Canvas so you do not keep making the same mistakes. I suggest re-doing assignment 8 at least 2 more times to make sure you know how. But don't stop there!  The links to the right will take you to two practice data sets, with answers. Try those out a couple of times. Finally, if you still need/want more practice, try running the 2 way mixed ANOVA that is in your book (chapter 10). If you run into problems, please see me or the stats intern for help.

What if I don't do well?

If you score less than 70% on this test, you will be given the option to retake it. But, the highest score you can receive on the retake is 80%. If you qualify for the retake, I will contact you and then special arrangements will be made as to when the retake will happen. I will accommodate schedules as much as possible, but if you want to take it after grades are due, it will mean signing an incomplete contract with me.
