The degree to which the results of a study can be extended to other settings or conditions describes

Extending a study's results to other settings or conditions is ecological generalizability.

Population generalizability concerns how well a sample represents its population, not settings.

Conclusions about a random sample stay within that sample and do not reach new settings.

Conclusions about information uncovered in a study describe findings, not their transfer.

Ecological generalizability is a form of external validity across contexts.

It is threatened when a study is run in an artificial or narrow environment.
