Module 12 Activity

Scenario

Produce the whole thing: a reproducible statistical report a colleague can rebuild and a reviewer can check.

What you build

A report with seven sections, in which no number was typed by hand.

Steps

1. Write the seven sections: question, data, method, result, uncertainty, limitations, next step.
2. Put the analysis in importable modules under src/ and cite their return values from the report through inline expressions.
3. Make the table, the test and the chart describe the same comparison at the same grain, choosing a chart that shows the distributions.
4. Compare the whole confidence interval to your pre-specified practical threshold and name which of the four verdicts applies.
5. Write the limitations before the conclusion, naming confounders, missingness and what was not tested.
6. Run the checklist, then do the destructive test: delete the outputs, restart the kernel, run everything and compare.

Evidence to hand in

• The seven-section report.
• The source, with zero numbers typed by hand.
• The table, test and chart of the same comparison.
• The verdict against the practical threshold.
• The limitations section.
• The result of the destructive rebuild, with versions recorded.

Review checklist

• All seven sections are present, including uncertainty and limitations.
• No number in the prose was typed rather than computed.
• The chart shows distributions, not just two means with error bars.
• The verdict names which of the four outcomes applies.
• The outputs were deleted, the kernel restarted, and everything rebuilt and compared.
