-
Syllabus Day (i.e. Welcome)
tl;dr: This lecture discusses the syllabus and outlines course expectations for the rest of the semester. -
Scientific Study of Politics
tl;dr: This is a gentle lecture on how to think about the study of politics scientifically. -
EITM and Science as Simplification
tl;dr: Another gentle lecture, this one on hypothetico-deductivism and the EITM framework. -
How to Do a Literature Review
tl;dr: Cribbed from a blog post and 2014 presentation, here's how I recommend students approach a literature review. -
On Theory-Writing
tl;dr: A discussion of some techniques to theory-writing, the hardest part of the research process (I think). -
Defining Concepts
tl;dr: A discussion of politics is ultimately conceptual. Political *science* entails operationalizing those concepts. -
Reliability and Validity
tl;dr: Ideally our measures are supposed to--consistently--capture the true concept without measuring anything else. -
Defining and Measuring Variables
tl;dr: Measurement is the heart of science. Let's talk about how we can categorize measurement. -
Central Tendency and Dispersion
tl;dr: We can describe variables by reference to what is typical and how typical is "typical." -
Framing Hypotheses
tl;dr: A quick primer on hypotheses, how to do them, and how not to do them. -
Making Comparisons
tl;dr: A discussions of types of relationships between variables and how to make comparisons between them. -
Probability and Counting for Political Science
tl;dr: A gentle introduction to some rules for probability and counting, with political science applications. -
Probability Distributions and Functions
tl;dr: A discussion of two types of distributions you'll see in political science applications. -
Controlled Comparisons and Controlled Relationships
tl;dr: A discussion of controlled comparisons and how to make them with or without experiments. -
Applied Controlled Comparisons
tl;dr: A primer on making controlled comparisons and estimating partial effects in simple cases. -
Random Sampling and Variation
tl;dr: A pivot into the world of inference, starting with a discussion of random sampling. -
Central Limit Theorem, Normal Distribution, and Inference
tl;dr: Inferring from sample to population is the core of what we do in applied statistics. Here's what the process resembles. -
Correlation and Linear Regression
tl;dr: A gentle introduction to correlation and linear regression as a means to describe a relationship between two interval-level variables. -
Extending OLS: Fixed Effects, Controls, and Interactions
tl;dr: Once you understand OLS in a simple bivariate context, its extensions are akin to adding more ingredients. -
Logistic Regression
tl;dr: If your DV is a dummy variable, you're going to want a logistic regression instead of OLS. It's really not daunting. -
Making the Most of Regression ("Divide By 4", Scaling)
tl;dr: You, the regression modeler, are also a storyteller. Here are two parlor tricks to help you tell your story. -
Post-estimation Simulation
tl;dr: Simulated estimated quantities of interest from a multivariate normal distribution using the regression model's parameters. -
Growth in a Time of Debt (or: a Workflow Gone Bad)
tl;dr: Does debt decrease GDP growth? If you have a bad research design and institutional prestige to burn, it does.
