Statistics Study Guide for the EPPP (2026)
A 39 page statistics guide for the EPPP and doctoral comps that teaches you to pick the right test from a study design and read the result.
What you get
- 39 pages on test selection: given the groups, measurement level and design, which test applies
- Interpretation: significant interactions, non-significant results, effect size and power
- The parametric tests and their non-parametric equivalents, ANOVA and its variants, regression, chi-square, and the assumptions behind each
- A worked-examples file where every practice question is solved in steps
Who it is for
EPPP candidates and doctoral students preparing for comps who need to read an analysis, not run one.
Why it is built this way
Almost nobody sitting a licensure exam needs to run a statistical analysis. They need to read one, and to pick the right test from a description of a study design.
So this guide runs on that logic. Given this many groups, this measurement level, and this design, which test applies. Then the interpretation: what a significant interaction actually means, why a non-significant result is not evidence of no effect, what effect size adds that a p value does not, and where power comes from.
