Part 1 – The case and the vocabulary
Part 1 sets out the case and the vocabulary: why social science is argued about at all, the matrix that separates reproducing from replicating, and the five analysts who reanalysed the claim that the day works on. It ends with R running on every machine.
| Work through | What you do | Timing |
|---|---|---|
| Slides, the credibility talk | What social science is for, false positives and forking paths, and the twenty-nine teams of the red-card study, grouped by the response distribution that each team assumed, a grouping to keep in mind for the rest of the day. | 18 minutes |
| Slides, the vocabulary | Why ‘replication’ names three operations; the data × analysis matrix; repeatability and credibility; the quick check on the matrix in peer review. | 15 minutes |
| Slides, Multi100 from the inside | What a Multi100 analyst received, the paper in brief, the two Multi100 tasks, how their results are put on a common scale, and a forest plot of the five analysts’ results, one row at a time. | 22 minutes |
| Slides, the workspace and the browser lab | The workspace, the report and the browser lab in one slide, and what the tools cannot do. | 8 minutes |
| Your workspace, or Browser lab Task 1 | Get to the point where a line of R runs and the panel of 270 country-years is in front of you. | 8 minutes, and the 30-minute break after it if you need more |
By the end of the part you have R running with the panel loaded, you can distinguish the three operations that go under the word ‘replication’, and you have the five analysts’ numbers in front of you as the puzzle that the rest of the day works on.
