Define causal effects, defend comparison designs and test the assumptions behind intervention decisions.
Learning path
- Causal estimands: name the unit, treatment and missing counterfactual
- Confounders and covariate timing: adjust only for variables with a valid role
- Randomized assignment: check balance and retain every assigned unit
- Observational overlap and weighting: know where the data can compare
- Difference-in-differences: compare changes under a defended trend assumption
- Sensitivity and placebo checks: state how the causal claim could fail
- Project: review the effect of a new lesson recommendation panel
Connected foundations
Use the earlier data and model boundaries as prerequisites.
