Descriptive Statistics Assignment Instructions

Overview

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.

Instructions

For the Descriptive Statistics Assignment, you will complete the Additional Exercises on pages 66 – 67 of your Pallant, SPSS Survival Guide textbook (Chapter 6). For convenience, due to page numbers being different in some eBooks, I am listing the assignments below.

Business

Data file: staffsurvey.sav. See classroom for file. See Appendix for details of the data file.

1. Follow the procedures covered in this chapter to generate appropriate descriptive statistics to answer the following questions.

(a) What percentage of the staff in this organization are permanent employees? (Use the variable employstatus.)

(b) What is the average length of service for staff in the organization? (Use the variable service.)

(c) What percentage of respondents would recommend the organization to others as a good place to work? (Use the variable recommended.)

2. Assess the distribution of scores on the Total Staff Satisfaction Scale (totsatis) for employees who are permanent versus casual (employstatus).

(a) Are there any outliers on this scale that you would be concerned about?

(b) Are scores normally distributed for each group?

Health

Data file: sleep.sav. See Appendix for details of the data file.

1. Follow the procedures covered in this chapter to generate appropriate descriptive statistics to answer the following questions.

(a) Are there any outliers on this scale that you would be concerned about?

(b) Are scores normally distributed for each group?

These are properly formatted tables (examples only):

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.
