Scientific Method Steps

- Question- Theory- Experiment/gather evidence- Test- Analyze - Iterate/replicate

Experimental Approach

Randomized study in which an experimental and a control group are compared using statistical methods

Quantitative Approach

Large-n study in which several "cases" (> 30) are compared using statistical methods

Qualitative Approach

Small-n study which uses a few, carefully selected cases to compare outcomes and causal processes

Comparative Method

A way to examine patterns of facts or events to narrow down what is important in terms of building a convincing argument. This is broken down into two methods: agreement and difference.

John Stuart Mill

method of agreement/difference

Independent Variable

a variable whose variation does not depend onanother and is often used to explain variation in another variable

Dependent Variable

a variable whose variation depends upon or can be explain by another variable

Challenges to Political Science Arguments

- Falsifiability (easily proven wrong)- Case Selection (non-diverse/cherry picking)- Spurious Correlation (correlation /= causation)- Omitted Variables (specify casual mechanism)- Reverse Causation (goes both ways)

To answer questions convincingly, you must

1 Select your cases carefully2 Test falsifiable hypotheses with evidence3 Specify your causal story

The worst arguments are...

- opinions based on stereotypes - belief that the past predicts the future- generalizations drawn from specific facts
