Course Syllabus


This course serves as an introduction to quantitative political methodology. We will first cover the general issues related to research design in political science. We will discuss problems of measurement and operationalization, validity and reliability of measurements, and the basics of writing research papers. After that we will proceed to the discussion of statistical methods and linear regression. We will start from first principles and gradually build skills required for thorough understanding of quantitative methods used in modern political science. Finally, we will also cover some of the topics from causal inference. The class strives to maintain the balance between building theoretical understanding and practical implementation of specific methods. I strongly believe that one is impossible without the other. On the one hand, understanding theoretical underpinnings of a specific method is pivotal for realizing the limits of its use. On the other hand, the theory separated from practical implementation tends to be a bit dry, so getting acquainted with data management and actual implementation of different models is also important.

    Exam takes place on 13 of June, 13.00 – 15.00. Please note that this time is exact: you need to start at 13.00 and end your attempt before 15.00. Only one attempt is allowed. Please, make sure your Internet connection is stable for the duration of the exam. This examination will be conducted in writing, online, with asynchronous proctoring. The platform for the exam is https://hse.student.examus.net Your computer, camera, and internet connection should satisfy the following technical specifications https://www.hse.ru/en/studyspravka/distance_stud_proctor Please login to the system 15 minutes before the examination starting time. The exam will start and end electronically, on time. Examus allows users to test their system before the exam. To take part in the exam, you will have to ◦ login in the system ◦ turn on/check that your camera is working ◦ confirm your identity ◦ test the system ◦ wait for the first question to appear on your screen. During examination, it is prohibited to ◦ leave the room ◦ communicate with other people in the room (if present), or through social media ◦ open any websites other than through links provided in the exam itself (i.e., the link to the calculator) ◦ use a phone or any other smart device ◦ look outside the camera field of coverage for more than 15 seconds During examination, you are allowed to ◦ use the paper to take notes and perform calculations Your desk should be clear of any objects except a mouse/keyboard, and, if you choose so, couple of clean pieces of paper. If your electronic system/connection is interrupted for less than 5 minutes, the examination can be resumed without penalties. If the interruption is longer than 5 minutes, you will have to re-take the exam at a later time and day. The exam will cover the material from the Module 3. Module 2 part of the course was covered in the Midterm and will NOT be covered in this exam. Exam will consist of a number of multiple choice, insert the number, short answer, and True/False questions. Multiple choice questions have only one correct answer. The total number of questions is 25. Each correctly answered question will give you 4% of the exam final grade. Incorrect answers get 0 % score. You will have a maximum of 2 hours (13.00 – 15.00) to complete the exam. Once you started, there will be only one attempt to complete the exam. The questions will appear one by one, with one question for page. Once you answered the question and confirmed the answer, the new question would pop up. You can go back to the question later if you wish to do so BEFORE you submit your attempt. You will NOT know the total score immediately as short answer questions require the manual grading. You will know the partial score. The maximum partial score is 64 %, or 6.4 out of 10. The weight of the final exam grade in the final grade for the entire course is 20%. Make-up final exam will be similar in form and complexity as the original final exam. In addition to the final exam, you have the access to the short practice test at the examus https://hse.student.examus.net platform. You should take this practice test couple of days prior to the actual exam in order to get acquainted with the system. Practice test is always available to you, and you can take it as many times as you want.
