### Instructions for Statistical Analysis1. **State Populations and Hypotheses:** Clearly define the populations being studied and the hypotheses to be tested.2. **Conduct a Factorial ANOVA in SPSS:** Use SPSS to perform a factorial ANOVA on the data collected.3. **Report All Results Using Proper APA Format:** Ensure all statistical results are reported in accordance with APA guidelines.4. **Indicate Interaction:** Specify whether interactions were noted, using or not using APA format as needed.5. **Significant Results and Post-hoc Tests:** Identify any significant results and conduct post-hoc tests where necessary.6. **Describe Study Results:** Summarize the findings of this study clearly.7. **Implications and Study Evaluation:** Discuss the implications, strengths, and weaknesses of the ANOVA.8. **Include SPSS Outputs:** Ensure that all relevant SPSS outputs are included in the final report.### Research ContextA social psychologist aims to assess whether the type of music college students listen to affects the number of study hours per week. Four music genres—rock and roll, jazz, country, and showtunes—were assessed. Each genre group included 10 students, comprising 10 males and 10 females (80 students total). Students’ study hours were recorded over a one-week period.### Data Table| Gender | Rock & Roll | Jazz | Country | Showtunes ||--------|-------------|------|---------|-----------|| Female | 2 | 6 | 8 | 8 || Female | 3 | 5 | 8 | 8 || Female | 2 | 6 | 6 | 8 || Female | 5 | 7 | 7 | 7 || Female | 2 | 6 | 6 | 6 || Female | 6 | 5 | 7 | 5 || Female | 4 | 5 | 8 | 6 || Female | 5 | 6 | 5 | 7 || Female | 3 | 7 | 6 | 7 || Female | 4 | 4 | 7 | 9 || Male | 3 | 6 | 9 | 5 || Male | 3 | 4 | 8 | 4 || Male | 3 | 3 | 4 | 5 || Male
