Which property means that a study would yield similar results if repeated?

• A. Validity
• B. Generalizability
• C. Reliability
• D. Credibility

Answer: (C)

Reliability is about consistency. If a study is reliable, repeating it under the same conditions should produce similar results, because the measurement tools and procedures are stable and not random. For example, if you give the same questionnaire to the same people later, you’d expect their scores to be similar (test-retest reliability), and if different researchers code the same responses, they should reach the same conclusions (inter-rater reliability). Reliability is about consistency, not necessarily about whether you are measuring what you intend (that’s validity), or whether the findings would apply to other groups or settings (generalizability). So repeating the study should yield similar results is the hallmark of reliability.
