Which statement best describes the balance between reliability and generalizability in the described study?

• A. Reliability was not addressed.
• B. External validity was proven beyond doubt.
• C. Reliability was ensured, while external validity remained uncertain.
• D. Both reliability and external validity were fully established.

Answer: (C)

Reliability is about how consistently the study’s measurements and procedures produce stable results, while generalizability (external validity) asks whether those results would hold in other people, settings, or times. If the study used standardized methods and clear procedures that yielded consistent results, that shows reliability was addressed. If, however, the sample or setting is limited—such as a specific group or a unique context—then we can’t assume the findings apply more broadly, so external validity remains uncertain. The best description, then, is that reliability was ensured, while external validity remained uncertain. The other options imply either that reliability wasn’t addressed or that generalizability was proven or fully established, which doesn’t align with a typical study that emphasizes precise measurement but notes limitations in applying results beyond its context.
