A good scientific experiment is reproducible. What does this mean?
A
The experiment must always produce exactly the same numerical results with no variation.
B
If the experiment is repeated under the same conditions, it should produce similar results.
C
The experiment’s results are valid only if they are surprising or counterintuitive.
D
The experiment is reproducible only if it uses a very large sample size.
Verified step by step guidance1
Understand the concept of reproducibility in scientific experiments: it refers to the ability to repeat an experiment under the same conditions and obtain results that are consistent or similar, not necessarily identical.
Recognize that exact numerical replication with zero variation is unrealistic due to natural variability and measurement error in experiments.
Identify that reproducibility means results should be similar enough to support the reliability of the findings, rather than requiring surprising or counterintuitive outcomes.
Note that while larger sample sizes can improve the reliability of results, reproducibility itself is about consistency of results under the same conditions, not solely about sample size.
Conclude that the best definition of reproducibility is: if the experiment is repeated under the same conditions, it should produce similar results.
