Problem

Participating students are randomly assigned to \(\text{two}~\text{study}~\text{methods}\). Analyze group comparability, causal scope, and the separate limit on population generalization.

Each participating student receives a random method label. The groups are comparable in expectation and support a causal method comparison, and random assignment also makes them representative of all students.

Each participating student receives a random method label. The groups are guaranteed identical on every confounder, so the method effect is proved with certainty and applies to every student.

Each participating student receives a random method label. The groups are comparable in expectation, supporting a causal method-effect comparison among participants; generalization depends on recruitment.

Each student chooses a study method. The groups can differ in motivation, so the design does not support a causal comparison; population generalization still depends on recruitment.
