Does the playing of music have a significant effect on workers’ productivity?

Suppose an I/O psychologist wants to study the effects of music on productivity in the workplace. She randomly assigns treatments to certain sections within the building – some sections will hear no music while working (No_music in Excel spreadsheet), some will hear music with no choice of what is being played (Music_set in the Excel spreadsheet), and some will hear music with input as to what music is played (Music_choice in the Excel spreadsheet). Does the playing of music have a significant effect on workers’ productivity? Enter answers to the following questions directly in the Response box (you can copy/paste the questions and then type your answers under each one), insert your ANOVA output in part e in the Response box, and ATTACH YOUR EXCEL FILE to your discussion response. 1. What are the Ho and Ha for this study (Be specific to the context of the study)? 2. What is your independent variable? 3. What is your dependent variable? 4. How many levels of the independent variable are there? 5. Why must you use a one-way ANOVA rather than an independent samples t-test to compare the mean productivity among the groups? 6. Insert your ANOVA Excel output here. 7. What is your F test statistic? 8. What is your p-value? 9. What is your decision regarding rejection? 10. What is your conclusion in context? 11. Based on the graphs, which group showed the highest productivity? 12. Which showed the lowest? 13. Do you think all of the groups are significantly different from each other? Why or why not? 14. What specific group differences would you expect to see in the post-hoc results?
