POL 52a Basic Statistics for Social and Political Analysis Fall 2016 Dr. Hande Inanc (e-mail: inanc@brandeis.edu, Office no: Golding 118) Time: 10:00-10:50, Monday, Wednesday and Thursday Room: Farber 101A Office hours: 14:00-15:30, Wednesdays Course description and learning goals: This course seeks to familiarize students with the fundamentals of social science data analysis. This consists of analyzing numerical data via descriptive and inferential statistics in order to better understanding social and political phenomena. The course is composed of three parts: Part I gives an overview of fundamental ideas in statistics such as types of variables (e.g. continuous, ordinal) and data (e.g. cross-sectional, longitudinal), and principles of sampling and population. In Part II students gain knowledge on describing statistics and learn about measures of tendency, distribution, dispersion and deviation. Inferential statistics are covered in Part III, with a focus on correlation and regression, and estimation, confidence intervals, and significance tests. Handson lab sessions help students learn how to carry out basic data preparation and analysis, as well as interpret outputs. Course requirements and Evaluation: No prior knowledge of statistics or advanced mathematics is required. Note that this is Four- Credit Course with three hours of class-time per week. This means that success is based on the expectation that students will spend a minimum of 9 hours of study time per week in preparation for class (readings, papers, exam preparation, etc.). Final grades will be determined by performance on the following: Class participation: 10% Take-home assignments (4 assignments): 20% Mid-term exam: 20% Final Project: 25% Final Exam: 25% * If you are a student with a documented disability on record at Brandeis University and wish to have a reasonable accommodation made for you in this class, please see me immediately. The following text will be available for purchase at the student bookstore, or can be rented or purchased online. It is required for all students. Agresti, Alan and Barbara Finley, (2013) Statistical Methods for the Social Sciences, 4 th Edition, Prentice-Hall. All other readings listed on the syllabus will be posted on LATTE. 1
Academic integrity: You are expected to be honest in all of your academic work. Please consult Brandeis University Rights and Responsibilities for all policies and procedures related to academic integrity. Students may be required to submit work to TurnItIn.com software to verify originality. Allegations of alleged academic dishonesty will be forwarded to the Director of Academic Integrity. Sanctions for academic dishonesty can include failing grades and/or suspension from the university. Citation and research assistance can be found at LTS - Library guides. Communication: I will communicate any changes in the syllabus, and snow days updates via a course mailing list. Please check LATTE and your Brandeis e-mail regularly. Use of technology in the classroom: None except for Stata in lab sessions. Participation grades will be docked if phones, computers, or tablets are used during class. *If there are exceptional circumstances that require you to use a computer, come talk to me and we can see about the possibility of an exception.
