Worked examples: the reproducible analysis behind every lesson
Every lesson we publish has a chapter called "the worked example". This is that document. Real data, the analysis that produced every number on screen, the source you can re-run, and the limits of what each method can tell you.
Which multiple-comparison correction do you actually need?
The reproducible worked example behind our multiple-comparisons lesson: 66 pairwise correlations on 1,599 wines, corrected four ways, cross-checked against R's own p.adjust.
McNemar's test or chi-square? Paired yes/no data, decided.
The reproducible worked example behind our McNemar lesson: 200 paired approve/deny decisions, agreement, kappa, and the four variants of the test.
Which ICC do you actually need?
The reproducible worked example behind our ICC lesson: the same ratings scored by different ICC forms, with confidence intervals.
Why we publish these
An analysis you cannot check is an opinion. Each document derives its figures live rather than quoting them, cross-checks against the reference implementation where one exists, and records what the review caught, including when the thing it caught was our own mistake.
