Causal Inference & Experimentation
Correlation is a liar that uses your voice
DAGs, A/B test engineering, CUPED, switchbacks, and observational methods — causal thinking for people who ship decisions.
Module
The Causal Question
What 'causes' even means, how to draw assumptions, and why a coin flip is the strongest algorithm
Module
Experimentation Engineering
Design, power, and variance — the machinery that makes a coin flip into a decision
Module
When Randomization Fights Back
Interference, invalidations, and the platform layer that keeps experiments honest at scale
Module
Observational Methods
No randomization? Reconstruct the counterfactual — and know the walls you can't climb
Capstone project
Correlation autopsy
Take a famous correlation (ice cream & drowning, or find your own) and reconstruct the causal story: confounders, possible experiments, and what evidence would settle it.
Deliverable: A causal diagram plus a short write-up of the confounder and how you'd test it.
