Diagnose the boundary issue
Each scenario is a short methods-section excerpt drawn from realistic graduate research designs. For each one, name whether the issue is an assumption, a limitation or a delimitation, then pick the response that best handles it. Coaching feedback explains why the plausible-looking wrong answers fall short.
