Who the Sample Excludes
Captions available
The idea
Every sampling decision excludes someone, and the excluded group defines the limit of what the study can claim.
In practice
A trial excluding patients with more than one condition, and the reader asking whether their own patients look like that.
Where people slip
This is unit 4's applicability question arriving from the designer's side. The exclusions you set become the transferability problem your readers inherit.
