Description

“There’s something magical about watching patterns emerge from data” Ben Goldacre (The Guardian, 11 June 2011)

Today’s world relies much on accumulation, presentation, and interpretation of large quantities of information. Statistics is a tool that enables us to organize our data in an efficient manner, and provides us with methods that help us understand the relationships that occur in our data and our growingly complex world. In this course, we will draw examples from multiple disciplines, such as political science, economics, medical sciences, biology to demonstrate how to search for and evaluate patterns in large amounts of data, as well as to interpret what these patterns tell us about the world. The material in this course proceeds gradually from simple descriptive statistics to more complex inferential statistics, such as linear regression. The course will primarily focus on developing substantive and precise understanding of the statistical concepts and their application to real-world examples using elementary computer programming in R statistical package.

Course objectives

Upon completion the course aims to provide the students with the following skills:
 Critically analyze various types of data and learn to select most appropriate statistical technique to answer a research question;
 use statistical programming to enter data, generate descriptive statistics and graphs, perform hypothesis tests and estimate regression models;
 confidently communicate and present statistical results to a variety of audiences – academic experts and policy-makers.

Mode of instruction

The course will consist of a combination of interactive lectures and lab seminars. Interactive lectures will mainly focus on developing the understanding of the main statistical concepts. Lab seminars are designed for the students to apply these concepts in a series of assignments using R statistical software.

Assessment method

Assessment for this course comprises of a cumulative examination, individual assignments, final report and participation.

  1. Two cumulative exams – 15% each. Weeks 4 and 8
  2. Weekly individual assignments: students will apply their skills obtained in the course to a question of their choosing. Each week they will complete a set of problems using data for their chosen topic – 30% total. Ongoing, weeks 1-7
  3. Final research report: Based on the findings from their individual assignments, students will, in the end, compile a research report focused on their chosen question (2000 words) – 20%. Due week 8, Friday at 17:00
  4. Participation: Participation comprises of two components 1) students’ engagement with the material during interactive lecture (10%) and 2) their ability to apply the reading material in a lab seminar(10%). Ongoing weeks 1-7
