Module 12 Activity

Scenario

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

What you build

A reproducible 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 sourced scripts and cite their objects from the report through inline expressions.
3. Make the table, the test and the chart describe the same comparison at the same grain, and choose 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 rebuild: delete the outputs, restart R, run everything, compare.

Evidence to hand in

• The seven-section report.
• The Quarto 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.

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, R restarted, and everything rebuilt and compared.
