1. A psychology student at a university is curious whether students in different majors have different reading preferences, or whether reading preference is independent of major. After doing some preliminary research, she chooses 3 different majors and recruits 10 volunteers from each major. She then asks them to choose their preferred type of book from fiction and nonfiction. The results are listed below. Perform a chi square test of independence (using an SPSS two-way contingency table analysis) to determine whether the proportions of reading preferences are the same or different across the major fields of study. Use the weighted cases method.
The steps will be the same as the ones you have been practicing in Part 1 of the assignment-the only difference is that you are now responsible for creating the data file as well. Remember to name and define your variables under the "Variable View," then return to the "Data View" to enter the data.

a) Paste the SPSS output.
b) Create a clustered bar graph depicting your results.
c) Write a current APA-style Results section based on your analyses. All homework Results sections must follow the example given in the SPSS tutorials and the Course Content document "Writing Results of Statistical Tests in Current APA Format" (note: you do not have to refer to a figure). Remember to include a decision about the null hypothesis.
