Which one of the following is established by the replication of research studies?
Show Hint
- Validity of the results
- Reliability of the results
- Interaction effect
- Mediation effect
The Correct Option is B
Solution and Explanation
Replication checks whether similar procedures yield consistent results across samples/settings \(\Rightarrow\) reliability (consistency/reproducibility).
Step 2: Why others are incorrect.
Validity concerns accuracy/truth of the inference (internal/external), which requires design and control, not just repeating the study. Interaction and mediation are specific statistical effects, not what replication {establishes}.
Final Answer: (B)
