Which of the following is included as a step of the scientific method in psychology?

• A. Replicate
• B. Randomize participants
• C. Debriefing
• D. Fabricate data

Answer: (A)

Replication is a fundamental part of the scientific process in psychology because repeating a study helps confirm that findings are reliable and not just a one-off result. By conducting the same or similar study again with different participants or settings, researchers test whether the observed effects hold up, strengthening confidence in the findings and supporting generalization beyond a single sample.

Randomizing participants is a technique used to reduce bias during experiments, ensuring groups are comparable, but it isn’t a step of the overall scientific method itself. Debriefing happens after data collection to inform participants and address ethics, which is important but not a core step in conducting the method. Fabricating data is unethical and has no place in the scientific process.

So, replication fits as the included step, supporting the reliability and accumulation of knowledge in psychology.
