This knowhow guides test selection, assumption diagnostics, and APA-style reporting for frequentist and Bayesian analyses in academic research.\n\n## Key Concepts\n\n### Frequentist vs Bayesian Framework\n\n| Aspect | Frequentist | Bayesian |\n|--------|-------------|----------|\n| Core output | p-value, confidence interval | Posterior distribution, credible interval |\n| Interpretation | \"How likely is this data if H0 is true?\" | \"How likely is H1 given the data?\" |\n| Null support | Cannot support H0 (only fail to reject) | Can quantify evidence for H0 via Bayes Factor |\n| Prior info | Not used | Incorporated via prior distributions |\n| Sample size | Requires adequate power | Works with any sample size |\n| Best for | Standard analyses, large samples | Small samples, prior info, complex models |\n\n### Statistical vs Practical Significance\n\nA statistically significant result (p < .05) may be trivially small in practice. Always report:\n- **Effect size**: Magnitude of the effect (Cohen's d, eta-squared, r, R-squared)\n- **Confidence interval**: Precision of the estimate\n- **Context**: Clinical/practical relevance in the domain\n\n### Common Effect Sizes\n\n| Test | Effect Size | Small | Medium | Large |\n|------|-------------|-------|--------|-------|\n| t-test | Cohen's d | 0.20 | 0.50 | 0.80 |\n| t-test (small n) | Hedges' g | 0.20 | 0.50 | 0.80 |\n| ANOVA | eta-squared partial | 0.01 | 0.06 | 0.14 |\n| ANOVA | omega-squared | 0.01 | 0.06 | 0.14 |\n| Correlation | r | 0.10 | 0.30 | 0.50 |\n| Regression | R-squared | 0.02 | 0.13 | 0.26 |\n| Regression | f-squared | 0.02 | 0.15 | 0.35 |\n| Chi-square | Cramer's V | 0.07 | 0.21 | 0.35 |\n| Chi-square 2x2 | phi coefficient | 0.10 | 0.30 | 0.50 |\n\nCohen's benchmarks are guidelines, not rigid thresholds -- domain context always matters.\n\n### Assumptions Overview\n\nMost parametric tests require:\n1. **Independence**: Observations are independent of each other\n2. **Normality**: Data (or residuals) are approximately normally distributed\n3. **Homogeneity of variance**: Groups have similar variances (for group comparisons)\n4. **Linearity**: Relationship between variables is linear (for regression)\n\nWhen assumptions are violated:\n- **Normality violated, n > 30**: Proceed -- parametric tests are robust with large samples\n- **Normality violated, n < 30**: Use non-parametric alternative\n- **Variance heterogeneity**: Use Welch's correction (t-test) or Welch's ANOVA\n- **Linearity violated**: Add polynomial terms, transform variables, or use GAMs\n\n### Test-Specific Assumption Workflows\n\n**T-test assumptions**: (1) Check normality per group with Shapiro-Wilk + Q-Q plots. (2) Check homogeneity with Levene's test. (3) If normality violated: Mann-Whitney U (independent) or Wilcoxon signed-rank (paired). If variance heterogeneity: use Welch's t-test.\n\n**ANOVA assumptions**: (1) Normality per group. (2) Homogeneity via Levene's test. (3) For repeated measures: check sphericity (Mauchly's test); if violated, apply Greenhouse-Geisser (epsilon < 0.75) or Huynh-Feldt (epsilon > 0.75) correction. (4) If normality violated: Kruskal-Wallis (independent) or Friedman (repeated).\n\n**Linear regression assumptions**: (1) Linearity via residuals-vs-fitted plot. (2) Independence via Durbin-Watson test (1.5-2.5 acceptable). (3) Homoscedasticity via Breusch-Pagan test + scale-location plot. (4) Normality of residuals via Q-Q plot + Shapiro-Wilk. (5) Multicollinearity via VIF (>10 = severe, >5 = moderate).\n\n**Logistic regression assumptions**: (1) Independence. (2) Linearity of log-odds with continuous predictors (Box-Tidwell test). (3) No perfect multicollinearity (VIF). (4) Adequate sample size (10-20 events per predictor minimum).\n\n### Specialized Test Categories\n\nBeyond the main decision flowchart, several specialized test families address specific data types:\n\n**Survival / time-to-event analysis**:\n- **Log-rank test**: Compares survival curves between groups (non-parametric)\n- **Cox proportional hazards**: Models time-to-event with covariates; assumes proportional hazards\n- **Parametric survival models**: Weibull, exponential, log-normal for known distributional forms\n- Use when outcome is time until an event (death, relapse, failure) with possible censoring\n\n**Count outcome models**:\n- **Poisson regression**: For count data where mean approximately equals variance\n- **Negative binomial regression**: For overdispersed counts (variance > mean)\n- **Zero-inflated models**: For excess zeros beyond what Poisson/NB predicts\n- Use when outcome is a count (number of events, incidents, occurrences)\n\n**Agreement and reliability**:\n- **Cohen's kappa**: Inter-rater agreement for categorical ratings (2 raters)\n- **Fleiss' kappa / Krippendorff's alpha**: Agreement for >2 raters\n- **Intraclass correlation coefficient (ICC)**: Continuous ratings reliability\n- **Cronbach's alpha**: Internal consistency of multi-item scales\n- **Bland-Altman analysis**: Agreement between two measurement methods (continuous)\n- Use when assessing measurement reliability or inter-rater consistency\n\n**Categorical data extensions**:\n- **McNemar's test**: Paired binary outcomes (2x2)\n- **Cochran's Q test**: Paired binary outcomes (3+ conditions)\n- **Cochran-Armitage trend test**: Ordered categories in contingency tables\n\n## Decision Framework\n\n### Test Selection Flowchart\n\n```\nWhat is your research question?\n|\n+-- Comparing GROUPS on a continuous outcome?\n|   |\n|   +-- How many groups?\n|   |   +-- 2 groups\n|   |   |   +-- Independent -> Independent t-test (or Mann-Whitney U)\n|   |   |   +-- Paired/repeated -> Paired t-test (or Wilcoxon signed-rank)\n|   |   +-- 3+ groups\n|   |      +-- Independent -> One-way ANOVA (or Kruskal-Wallis)\n|   |      +-- Repeated -> Repeated-measures ANOVA (or Friedman)\n|   |\n|   +-- Multiple factors? -> Factorial ANOVA / Mixed ANOVA\n|   +-- With covariates? -> ANCOVA\n|\n+-- Testing a RELATIONSHIP between variables?\n|   |\n|   +-- Both continuous?\n|   |   +-- Normal -> Pearson correlation\n|   |   +-- Non-normal or ordinal -> Spearman correlation\n|   |\n|   +-- Predicting continuous outcome?\n|   |   +-- 1 predictor -> Simple linear regression\n|   |   +-- Multiple predictors -> Multiple linear regression\n|   |\n|   +-- Predicting categorical outcome?\n|   |   +-- Binary -> Logistic regression\n|   |   +-- Ordinal -> Ordinal logistic regression\n|   |\n|   +-- Predicting count outcome?\n|   |   +-- Equidispersed -> Poisson regression\n|   |   +-- Overdispersed -> Negative binomial regression\n|   |   +-- Excess zeros -> Zero-inflated Poisson/NB\n|   |\n|   +-- Time-to-event outcome?\n|       +-- Compare survival curves -> Log-rank test\n|       +-- With covariates -> Cox proportional hazards\n|\n+-- Testing ASSOCIATION between categorical variables?\n|   +-- Expected cell count >= 5 -> Chi-square test\n|   +-- Expected cell count < 5 -> Fisher's exact test\n|   +-- Ordered categories -> Cochran-Armitage trend test\n|   +-- Paired categories -> McNemar's test\n|\n+-- Assessing AGREEMENT / RELIABILITY?\n    +-- Categorical, 2 raters -> Cohen's kappa\n    +-- Categorical, >2 raters -> Fleiss' kappa\n    +-- Continuous ratings -> ICC\n    +-- Two measurement methods -> Bland-Altman analysis\n    +-- Internal consistency -> Cronbach's alpha\n```\n\n### Quick Reference Table\n\n| Research Question | Data Type | Normal? | Test | Non-parametric Alternative |\n|-------------------|-----------|---------|------|---------------------------|\n| 2 independent groups | Continuous | Yes | Independent t-test | Mann-Whitney U |\n| 2 paired groups | Continuous | Yes | Paired t-test | Wilcoxon signed-rank |\n| 3+ independent groups | Continuous | Yes | One-way ANOVA | Kruskal-Wallis |\n| 3+ repeated groups | Continuous | Yes | Repeated-measures ANOVA | Friedman test |\n| 2 variables | Continuous | Yes | Pearson r | Spearman rho |\n| Predict continuous | Mixed | -- | Linear regression | -- |\n| Predict binary | Mixed | -- | Logistic regression | -- |\n| Predict counts | Count | -- | Poisson / Negative binomial | -- |\n| Time-to-event | Survival | -- | Cox PH / Log-rank | -- |\n| 2 categorical | Categorical | -- | Chi-square / Fisher's exact | -- |\n| Rater agreement | Categorical | -- | Cohen's kappa / Fleiss' kappa | -- |\n| Method agreement | Continuous | -- | Bland-Altman / ICC | -- |\n\n## Best Practices\n\n1. **Pre-register analyses** when possible to distinguish confirmatory from exploratory findings. Specify primary outcome, tests, and correction methods before data collection\n2. **Always check assumptions before interpreting results**. Run normality tests (Shapiro-Wilk), homogeneity tests (Levene's), and residual diagnostics. Document results even when assumptions are met\n3. **Report effect sizes with confidence intervals** for every test. p-values alone are insufficient -- effect sizes convey practical importance\n4. **Report all planned analyses** including non-significant findings. Selective reporting inflates false positive rates\n5. **Use appropriate multiple comparison corrections**. Bonferroni (conservative), Holm (step-down, less conservative), or FDR/Benjamini-Hochberg (for many tests). Choose based on the number of comparisons and acceptable error rate\n6. **Visualize data before and after analysis**. Box plots for group comparisons, scatter plots for correlations, residual plots for regression diagnostics\n7. **Conduct sensitivity analyses** to assess robustness: re-run with outliers removed, different transformations, or alternative tests\n8. **Anti-pattern -- p-hacking**: Testing multiple outcomes, subgroups, or model specifications until p < .05 inflates false positives. Pre-register to avoid\n9. **Anti-pattern -- HARKing** (Hypothesizing After Results are Known): Presenting exploratory findings as confirmatory undermines scientific integrity\n10. **Anti-pattern -- misinterpreting non-significance**: Failure to reject H0 does not mean H0 is true. Use Bayesian methods or equivalence testing to support null\n\n## Common Pitfalls\n\n1. **Misinterpreting p-values as probability of the hypothesis being true**. p-values measure P(data | H0), not P(H0 | data). *How to avoid*: Use precise language: \"If the null hypothesis were true, the probability of observing data this extreme is p = ...\"\n\n2. **Confusing statistical significance with practical importance**. A large sample can make trivially small effects significant. *How to avoid*: Always report and interpret effect sizes alongside p-values\n\n3. **Running post-hoc power analysis after a non-significant result**. Post-hoc power is a mathematical function of the p-value and adds no new information. *How to avoid*: Use sensitivity analysis instead -- determine what effect size the study could detect at 80% power\n\n4. **Ignoring assumption violations and proceeding with parametric tests**. *How to avoid*: Run assumption checks systematically. Use Welch's corrections, non-parametric alternatives, or transformations when violated\n\n5. **Multiple comparisons without correction**. Running 20 tests at alpha = .05 gives ~64% chance of at least one false positive. *How to avoid*: Apply Bonferroni, Holm, or FDR correction. Report both corrected and uncorrected p-values\n\n6. **Treating ordinal data as continuous**. Likert scales are ordinal -- means and standard deviations assume equal intervals. *How to avoid*: Use non-parametric tests (Mann-Whitney, Kruskal-Wallis) or ordinal regression\n\n7. **Ignoring missing data patterns**.
