Course Goals

The goal of this course is to give you the ability to understand, explain, and perform social science research, with a special focus on data analysis and causal reasoning. By the end of the semester, students will be able to:

  • Evaluate claims about causality in social science research
  • Summarize and visualize data effectively
  • Apply linear regression to analyze political and social data
  • Understand and quantify uncertainty in data analysis
  • Use professional tools including R, RStudio, git, and GitHub

You will be able to read and understand the methodology of most academic articles in the social sciences, and have a foot in the door of the data science world.

Course Format

The course consists of two 75-minute lectures per week and one required weekly discussion section led by Teaching Fellows. Lectures introduce key ideas in statistical inference and causal reasoning, grounding them in practical social science research. Students will learn to program in R, work with real-world datasets, and build both intuitive and technical understanding of modern empirical methods.

Discussion sections provide hands-on practice with statistical software and space to work through problem sets under Teaching Fellow guidance. Students should expect an interactive learning environment that moves between conceptual foundations, implementation, and interpretation.

Reminder: You can attend any section in a given week regardless of which one you're officially registered for.

Assignments and Grading

Component Weight Description
Problem Sets (4) 40% Four applied data analysis assignments using real-world datasets. Due Wednesdays at 11:59pm via Gradescope.
Midterm Exams (2) 40% Two in-class exams (no notes, no computers).
Final Project 20% Independent data analysis on a topic of your choice. Individual or groups up to 3.

Late Policy: Late submissions lose 10% per day (e.g., 1 day late = 90% max score). After 7 days, late work receives a zero. This applies to both problem sets and final project milestones.

Course Policies

Technology Policy

  • No phones in class (put them away, turned off)
  • No laptops for taking notes
  • Tablets with stylus are permitted, as is analog note-taking
  • Laptops may be used when we code, but otherwise should be put away
  • Accommodations are available for students who need them

AI Policy

See the AI Policy page on Canvas. The goal of this course is for you to learn to think with data. Using AI to generate answers defeats that purpose and will leave you unprepared for exams, which are completed in-class without AI assistance.

Submission and Grading

All assignments and exams will be submitted through Gradescope, accessed directly through Canvas. Regrade requests must be submitted through Gradescope within one week of grades being posted with a clear explanation.

Getting Help

If you're struggling, please reach out early. Come to office hours, attend TF sections, and use the course discussion board. Learning statistics is hard—confusion is normal and expected. What matters most to me is what you actually learn.
