Quantitative Research Methods


Admission requirements

Completion of compulsory Year 1 courses Introduction to Statistics and Mathematical Modeling / Mathematical Reasoning.


Today's world relies much on the 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 increasingly complex world. In this course, we will draw examples from multiple disciplines, such as political science, economics, medical sciences, and 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 covers data display, statistical inference, regression and experimental design. The course will primarily focus on developing substantive and precise understanding of the various quantitative research designs and corresponding statistical methods. Students will develop individual projects, applying their knowledge to real-world problems using elementary computer programming in the R statistical programming package.

Course Objectives

This course is designed to be accessible for students at all levels of mathematical skill. The focus is put on developing conceptual understanding of statistics without heavy reliance on rigorous mathematical background. The knowledge obtained from this course should provide solid background for students who wish to continue their statistical education with more advanced courses as well as prepare students to perform their own statistical analyses in their coursework and beyond.

Upon completion the course aims to provide the students with the following skills:

  • Apply scientific research process, including theory formulation and hypothesis testing.

  • Critically analyze various types of data and learn to select most appropriate elementary statistical technique to answer their research question;

  • Use statistical programming to enter data, generate descriptive statistics and graphs, and estimate basic statistical models.

  • Communicate and present statistical results to a variety of audiences – academic experts and policy-makers.
