Research Methods Study Guide for the EPPP (2026)
A 36 page research methods guide for the EPPP and doctoral comps, built around one skill: what you can and cannot conclude from a described study.
What you get
- Internal and external validity, the threats to each, and the design feature that controls for it
- Experimental, quasi-experimental and correlational designs and what each licenses you to claim
- Sampling, and random assignment against random selection
- Confounds, mediators and moderators
- Research ethics, IRB thresholds and informed consent in research settings
- A separate practice question file with the design tables worked through
Who it is for
EPPP candidates and doctoral students preparing for comps.
Why it is built this way
Research methods questions on licensure exams are rarely about methodology for its own sake. They describe a study and ask what you can and cannot conclude from it.
