Objectives and Structure of the Course
This course will be driven by a practical, hands-on approach: The most effective way to learn statistics is by actively engaging in doing the statistical analysis.
The material presented in the course will be analyzed using techniques that are typically taught in a traditional introductory course (see the syllabus for a description). The cases will be grouped by broad statistical topics, and arranged by topics in a sequence that is conventionally followed in a beginning course. There will be a certain progression in the material: concepts from data analysis will be used in subsequent cases dealing with applied probability, and statistical inference, and so forth.
This course is part of a three-quarter sequence. This course will cover questions of assessing the weight of evidence and more sophisticated models including regression-based methods. The course may be preceded by CSSS 320 “Evaluation of Evidence”, a course in quantitative thinking offered in the Autumn, or by CSSS 321 “Case-based Social Statistics I”, covering the fundamental ideas of statistical reasoning and the central role that measurement plays. It is offered in the Spring and also introduces methods for exploratory data analysis, and the fundamentals of probabilistic reasoning. Throughout these courses the understanding of the underlying concepts will be stressed. Details of the topics and cases for both courses are provided in the syllabus.
This sequence is part of the curriculum of the new Center for Statistics and the Social Sciences (CSSS), with funding from the University Initiatives Fund. The CSSS is includes faculty members from the Department of Statistics and a broad-range of social science disciplines including Anthropology, Economics, Geography, Political Science, and Sociology. This curriculum is been developed to complement and strengthen the quantitative methods course offerings for social science students at both the undergraduate and graduate levels.
Structure of the Course
There will be three lectures, and “laboratory” session, and a “question session” each week.
The laboratory is on Tuesday and a question session on Friday.
The objective of the laboratory is to help students develop the skills necessary to analyze real data and hence learn the underlying statistical concepts. This laboratory serves a similar role as a chemistry or physics laboratory does; it provides an opportunity for you to interactively uncover the information in a data set in the context of answering questions about the situation that the data relates to. The idea is to train yourself in the process of analyzing real data, which is a skill that you will need here at UW and in your post-UW years.
Each week, there will be a assignment to complete by the next week. The assignment may have up to three parts:
1. Readings from the textbook Mind On Statistics and in CyberStats
2. Interactivities to explore in CyberStats
3. Exercises to be turned in, from Mind On Statistics and/or CyberStats
The question session each week will focus on material from Exercises and Interactivities.

Cyberstats and Intranet Resources
The course will make extensive use of the web as a source of statistical information and for the course materials. Much of the conduct of the class will take place via the web.
In particular we will use the web-based courseware Cyberstats. It is a resource with many components (e.g., units, exercises). We will use it to visualize the behavior of statistical concepts through the use of conceptual software.
To use Cyberstats, you must signup.
Where appropriate, reports and homeworks will be submitted and reviewed over the UW intranet.
Class Discussion Forum
I will be using the class discussion forum to provide discussion of issues in class and related questions. For questions that might be of interest to other students, please use the discussion forum rather than solely emailing me. Example of questions are about interesting articles you have seen in the media, problems with access to resources, homework or computer questions. Enjoy!
Please regularly consult this class home page and read the messages on the discussion forum. It will contain lecture notes, homework, solutions and course information.
Computer Usage and Software
The computer is the scientific laboratory of the applied researcher in quantitative fields. As such this course requires the student to develop a degree of comfort and competence “in the lab”.
Course Requirements and Grades
The grade for this class will be based on a mid-quarter exam (35%), a final exam (35%), laboratory work (10%) and homework assignments (20%). The assignments and laboratory work will involve the analysis of real data sets using appropriate computer software.
The examinations are closed-book and are non-cumulative. Students will be allowed to bring a single page of formulae to the exam. You should also bring a calculator.
Assignments and Laboratories
None of the assignments or the laboratory are optional. All homework will be due at the beginning of the class on the assigned due date. To allow for unexpected emergencies or extraordinary bad luck, the lowest homework score will be omitted from the grade computation.
The purpose of the assignments and laboratories is to develop facility in statistical thinking through regular practice and to provide you with regular feedback on your performance throughout the course. The assignments will be used mostly to determine borderline cases, such as the difference between a B+ and an A-. However I regard the assignments as essential to the course: failure to do the assignments will result in a significant penalty to your grade!
Don't hand in assignments late! This is the reason most students who get in trouble do so! It will affect your grade Assignments that are up to one week late will be penalized points; assignments from one to two weeks late will be penalized 3 points; assignments from two to three weeks late will be penalized 6 points; assignments more than three weeks late will not be accepted.
Discussion of homework problems is encouraged. However, each student is required to prepare and submit solutions (including computer work) to the assignments and project on their own; solutions prepared “in committee” are not acceptable. Duplication of homework solutions and computer output prepared in whole or in part by someone else is not acceptable and is considered plagiarism. If you receive assistance from anyone, you must give due credit in your report. (Example: “Since the data are all positive, and skewed to the right, a logarithmic transformation is clearly appropriate as a next step. I thank David Cox for pointing this out to me.”)
The two teaching assistants (Leah Jager and JJ Wawrzaszek) will be available to discuss questions you may have about the homework. They will also conduct the “question session” to discuss questions that arise in classes and exercises.
This course is time consuming. If you do “A” work you will receive an “A” grade. The grade of incomplete will be given only in clear cases of emergency.
I welcome comments or suggestions about the course at any time, either in person, by letter, or by anonymous email. Please feel free to use these ways make comments to me about any aspect of the course.
