The big picture: One-Sample Median Test
Does the population’s middle value differ from a prespecified benchmark?
Why a policy analyst should care
When a policy question concerns the typical or middle outcome, a one-sample median comparison keeps the estimand tied to that benchmark without letting a few extreme values redefine it.
Follow the idea from the opening question to a practical decision. These are the conceptual moves this module will develop:
1 Question Is the population middle different from the benchmark?
2 Explore Count observations on either side of the benchmark
3 Formalize A sign test for a hypothesized median
4 Transfer Keep the median estimand explicit
