Why is repeating experiments important?

• A. It saves time.
• B. It ensures results can be reproduced and are reliable.
• C. It eliminates the need for controls.
• D. It increases the complexity of data.

Answer: (B)

Repetition is essential to verify that findings are not just a one-off result. By performing the experiment multiple times, you check for random errors and see how much the measurements vary. When the same outcome appears across several trials, the results become reproducible and reliable, forming a solid basis for conclusions. This allows us to quantify uncertainty, use statistics to assess significance, and trust that others could observe the same pattern under similar conditions. Repetition also helps catch mistakes, instrument drift, or sample issues that might skew a single trial. The idea isn’t to save time or to add unnecessary complexity. It’s about building confidence in the results and ensuring that conclusions are robust. Controls are still needed, and repetition complements them rather than replaces them.
