1. Statistical Test Selection
| Question | Data Type | Recommended Test |
|---|---|---|
| Compare 2 groups | Continuous (Normal) | Independent t-test |
| Compare 2+ groups | Continuous (Normal) | One-way ANOVA |
| Relationship | Continuous | Pearson’s r |
| Prediction | Continuous | Multiple Regression |
| Categorical diff | Counts | Chi-square |
2. Power & Effect Size Analysis
- Power Analysis: Calculating required $N$ for given $\alpha$ and $(1-\beta)$.
- Effect Sizes: Cohen’s $d$, Pearson’s $r$, $\eta^2$, Odds Ratios.
3. Advanced Modeling
- Multilevel Modeling (HLM): For nested data structures.
- Structural Equation Modeling (SEM): For latent variable analysis.
- Non-parametric alternatives: Mann-Whitney U, Wilcoxon, Kruskal-Wallis.
