Your question is Reproducible Statistical Code. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How do you ensure reproducibility in your statistical code?
Give a practical response covering data and code versioning, dependency management, random-number control, deterministic preprocessing, validation checks, and result reporting. Demonstrate how you would verify that repeated executions produce the same statistical outputs, while distinguishing exact reproducibility from results that may vary because of randomized sampling or software changes.
