Which term describes the act of repeating an investigation to verify results?

• A. Reproduction
• B. Repeat/Repetition
• C. Replication
• D. Recheck

Answer: (B)

The idea being tested is how scientists verify results by doing the same study again. Repetition means performing the exact same investigation again, using the same methods and materials, to see if you get the same results. This helps show that findings aren’t just a fluke or due to random chance, reinforcing that the result is reliable. In practice, repeating an experiment to confirm what happened originally is exactly what repetition is about, making it the best fit for this description. Other terms have different shades of meaning. Reproduction is more about copying a system or process, not about re-running the investigation. Replication is a closely related idea and is often used to describe repeating a study, sometimes by different researchers or under varied conditions to test consistency more broadly. Recheck means double-checking data or calculations, rather than redoing the entire experiment.
