Part 4 – Exploration, preregistration and archiving

Slides. Open the deck at this part in its own tab, or follow it on the slides page.

Part 4 opens the menu of alternatives to the specification you reproduced, has you explore it and put a dot on the class chart, then asks for the one analysis you would defend, preregistered in your report before it runs. The last stretch covers where a finished reanalysis is archived, and what a version history, a licence and a registration each add to the chance that someone else can find and re-run it.

Work through	What you do	Timing
Specification menu and slides	The axes you choose from, the three levels they sort into, what Task 2 of Multi100 left open, the ground rules for the menu and the claim-alignment convention that puts every result on one scale.	15 minutes
Task 4 in the workspace or on the Browser lab, then Multiverse	Call try_spec() three or four times, changing one argument at a time, print them with my_experiments(), then submit the one you would defend with submit_exploration(). Your dot is drawn on the chart as an open circle.	20 minutes
Multiverse and slides	The exploratory dots from the class, read against the full curve and the five analysts.	12 minutes
Slides	The critics of multiverse analysis, the argument that a fully specified question has one correct analysis, and what preregistration settles and what it leaves open.	8 minutes
Slides, archiving and registering, with Reproducibility repositories and Social science data sources as the companions	The three OSF addresses connected with the case and what each of them is for; the Multi100 preregistration, which is the protocol that the project filed for itself; the two preregistration templates, and the eight AsPredicted questions with your answers already mapped onto them.	12 minutes
The report skeleton in the workspace, or Browser lab Task 5	Complete the preregistration block before you run anything, translate it into model syntax yourself, run it, render the report, and submit with report_result(). Your declared result is drawn on the chart as a filled circle.	18 minutes
Slides	Two points from the literature, the single analytical path, and what you take with you.	5 minutes

By the end of the part you have an exploratory dot and a declared dot on the class chart, a rendered report that contains a preregistration block with its result underneath, and the addresses at which a reanalysis like yours is archived and registered.
