Curriculum

15 short video lessons — each with the exact R code and a downloadable script. Work through them in order.

1 ### Table 1 with gtsummary Baseline characteristics by group, with an automatic test per row.

2 ### Correlation: Pearson & Spearman A correlation test with a CI, and a scatter plot.

3 ### Chi-square & Fisher’s Test Test whether two categorical variables are associated.

4 ### Odds Ratio, Relative Risk & NNT The three headline risk measures from a 2×2 table.

5 ### ANOVA & Post-hoc Tests Compare 3+ group means, then Tukey’s pairwise test.

6 ### Non-parametric Tests Wilcoxon, Mann-Whitney and Kruskal-Wallis.

7 ### Effect Size: Cohen’s d How big is the difference, beyond the p-value.

8 ### Multiple Linear Regression Predict a numeric outcome from several variables.

9 ### Logistic Regression & Odds Ratios Adjusted odds ratios with CIs, plus ROC and AUC.

10 ### Kaplan-Meier Survival Curves Survival by group, the curve, and the log-rank test.

11 ### Cox Proportional Hazards Hazard ratios with the PH assumption check.

12 ### Diagnostic Test Accuracy Sensitivity, specificity, PPV, NPV and likelihood ratios.

13 ### Cohen’s Kappa Agreement between two raters, beyond chance.

14 ### Cronbach’s Alpha The internal consistency of a scale.

15 ### Sample Size & Power Plan the study before you collect the data.
