SYLLABUS SOC 5070/STAT 5070 SPRING 2013 STATISTICAL METHODS FOR THE SOCIAL SCIENCES Class meets Mondays at 3:10-5:40pm in CR 207 Instructor: Dr. Anna Zajacova Email: zajacova@uwyo.edu Office: 421 Ross Hall Office hours: Mondays and Thursdays, 11:00 am -12:30 pm COURSE DESCRIPTION: The majority of research in the social sciences is quantitative. The most widely-used quantitative approach is regression modeling, meaning analysis where some dependent variable is modeled as a function of one or more predictors. This course will provide a solid foundation in the multiple linear model as the basic form of the regression approach. We will focus on applying the techniques appropriately, interpreting the findings and writing them up for a research paper or a thesis, as well as diagnosing and correcting potential problems. We will also briefly cover some extensions of this basic model, in particular logistic regression for binary dependent variables. The focus of the course is on applied statistics; we will be using the Statistical Package for the Social Sciences (SPSS) throughout the semester to conduct analyses. COURSE OBJECTIVES: At the completion of the class, students will be able to Understand basic concepts of descriptive and inferential statistics Conduct and interpret a statistical analysis for a research paper of a master's thesis Comprehend and critically evaluate most quantitative social science research articles Write solid quantitative reports as may be required in your future employment Gain an appreciation for rigorous statistical thinking Apply the analytical reasoning from the class to other areas of your study and beyond COURSE STRUCTURE: The classes will combine lectures with student participation, individual and group exercises, hands-on SPSS work, and writing up findings. In order to participate in the class, students are expected to complete the assigned readings and homework prior to the class. PREREQUISITES: STAT 2070: Introductory Statistics for the Social Sciences or an equivalent introductory statistics class. Basic knowledge of elementary applied descriptive and inferential statistics is assumed although fundamentals will be briefly reviewed at the beginning of the course. Prior experience with SPSS statistical software is not required. 1 SYLLABUS SOC 5070/STAT 5070 SPRING 2013 REQUIRED TEXTS: Alan Agresti and Barbara Finlay (2008). “Statistical Methods for the Social Sciences” (4th Edition). ISBN-10: 0205646417. Marija Norusis (2008). “SPSS 16.0 Guide to Data Analysis” (2nd Edition, Paperback). ISBN-10: 0136061362. GRADING: Homework, 34% of the final grade. There will be weekly homework assignments, to be turned in at the beginning of class. Each week will be worth the same proportion of the total 34%. The lowest homework score is dropped when calculating the final grade. In-class or take-home tests, 24% of the final grade. There will be 3 tests, each worth 8% of the final grade. The tests will include a combination of paper-and-pencil problems and working with the statistical software to analyze data. The dates of the tests are February 18, March 25, and April 29. Final project, 36% of the final grade. The project will be a complete though relatively brief research paper. The paper will include an abstract, introduction, data and methods, results, discussion, tables/figures, and references. The total length is about 12-18 pages, double-spaced with Times New Roman font 12 or equivalent. The emphasis will be on appropriate data analyses and clear interpretation of findings, but also on solid conceptual framing of the research question, adequate literature review, and discussion of the results. The topic will be chosen by the students after consultation with the instructor, within constraints of the available data. The paper will be developed during the semester in 3 discrete gradual stages. You will begin with a brief description of the data and a sketch of your conceptual argument for the paper. Gradually you will add analyses and their interpretation. Finally, you will pull everything together in the complete. I will provide comments at each stage to help you develop the project to a successful completion. The three stages will be worth 9%, 11%, and 16%, respectively. A hard copy of the final draft is due in my office on May 9 by 5:00pm. We will discuss additional specifics of the project during the semester. Class participation, 6% of the final grade. This part will capture class preparation (readings completed as assigned prior to class), attendance and appropriate participation in discussions, focused work during classes, etc. Please note. There will be no makeup tests for unexcused absences. Unexcused late assignments may be penalized 20% for each day past due, including holidays and weekends. Late homework may not be accepted. 2 SYLLABUS SOC 5070/STAT 5070 SPRING 2013 IMPORTANT DATES: January 14 First class January 21 University holiday, no class February 18 Test #1 March 18 Spring break, no class March 25 Test #2 April 1 Project stage #1 due April 22 Project stage #2 due April 29 Last class.

Students are responsible for all announcements, lecture notes, and exercises we cover in class even if there is a valid reason to miss a class. If you miss a class, please contact your colleagues first to get information about the missed class and class notes. Please make sure you have printing privileges. We will be doing a lot of hands-on work in class and you may need to print documents out to share with your colleagues. Students' rights and responsibilities: Please refer to the University of Wyoming Regulation 8-30 for information concerning your rights and responsibilities as a University of Wyoming student.
