Mean differences analysis in business and health data

MEAN DIFFERENCES ASSIGNMENT You will take part in several data analysis assignments in which you will develop a report using tables and figures from the IBM SPSS output file of your results. Using the resources and readings provided, you will interpret these results, test the hypotheses, and write up these interpretations. This assignment has three parts: Complete the Additional Exercises on page 261 (Chapter 17) Business Data file: staffsurvey.sav. See Classroom for file. See Appendix for details of the data file. 1. Follow the procedures in the section on independent-samples t-tests to compare the mean staff satisfaction scores (totsatis) for permanent and casual staff (employstatus). Is there a significant difference in mean satisfaction scores? Health Data file: sleep.sav. See Classroom for file. See Appendix for details of the data file. 1. Follow the procedures in the section on independent-samples t-tests to compare the mean sleepiness ratings (Sleepiness and Associated Sensations Scale total score: totSAS) for males and females (gender). Is there a significant difference in mean sleepiness scores? Complete the Additional Exercises on page 280 (Chapter 18) Business Data file: staffsurvey.sav. See Classroom for file. See Appendix for details of the data file. 1. Conduct a one-way ANOVA with post-hoc tests (if appropriate) to compare staff satisfaction scores (totsatis) across each of the length of service categories (servicegp3). Health Data file: sleep.sav. See Classroom for file. See Appendix for details of the data file. 1. Conduct a one-way ANOVA with post-hoc tests (if appropriate) to compare the mean sleepiness ratings (Sleepiness and Associated Sensations Scale total score: totSAS) for the three age groups defined by the variable agegp3 (37 or under, 3850, 51+). Complete the Additional Exercises on page 289 (Chapter 19) Business Data file: staffsurvey.sav. See Appendix for details of the data file. 1. Conduct a two-way ANOVA with post-hoc tests (if appropriate) to compare staff satisfaction scores (totsatis) across each of the length of service categories (servicegp3) for permanent and casual staff (employstatus). Health Data file: sleep.sav. See Appendix for details of the data file. 1. Conduct a two-way ANOVA with post-hoc tests (if appropriate) to compare male and female (gender) mean sleepiness ratings (Sleepiness and Associated Sensations Scale total score: totSAS) for the three age groups defined by the variable agegp3 (37 or under, 3850, 51+). General Instructions As doctoral students, your assignments are expected to follow the principles of high-quality scientific standards and promote knowledge and understanding in the field of criminal justice. You should apply a rigorous and critical assessment of a body of theory and empirical research, articulating what is known about the phenomenon and ways to advance research about the topic under review. Research syntheses should identify significant variables, a systematic and reproducible search strategy, and a clear framework for studies included in the larger analysis. Manuscripts may be written in first person (I). All manuscripts should be clearly and concisely written, with technical material set off. Please do not use jargon, slang, idioms, colloquialisms, or bureaucratese. Use acronyms sparingly and spell them out the first time you use them. Please do not construct acronyms from phrases you repeat frequently in the text.

Structure of Assignment Paper For purposes of this assignment, there is no layout structure required as far as the setup of this paper, with one exception. I would appreciate it if you used separate headers for questions. Sub- headers are also allowed but not required. Questions should strive to be no less than 100 words each with no maximum limit. There is no overall page limit. I expect all papers to be in the latest APA edition, properly cited, and tables attached in the correct format. Note: Your assignment will be checked for originality via the Turnitin plagiarism tool.
