Which statement about reproducibility is correct?

• A. Reproducibility requires access to data and methods to reproduce results
• B. Reproducibility is optional in most research
• C. Reproducibility means results will be identical across all analyses
• D. Reproducibility is achieved by publishing in open access only

Answer: (A)

Reproducibility means others can verify findings by repeating the analysis exactly as it was done, which requires access to the data and the methods used. When data, code, and the detailed steps (including software versions and parameters) are available, another researcher can run the same workflow and obtain the same results, helping confirm accuracy and build trust. Open access to the publication helps sharing knowledge, but it doesn’t by itself guarantee reproducibility unless the underlying data and methods are also shared. Reproducibility is about the same process applied to the same data producing the same outputs, not about every possible analysis yielding identical results.
