Research Survey Validation and Replication
How validation reports, audit trails, codebooks, and replication files make survey research easier to trust and review.
In Brief
Validation is a chain of evidence rather than a badge. Researchers should be able to see that randomization behaves as intended, follow the path from responses to estimates, inspect the exports, and understand how the final analysis file was produced.
What Validation Can Show
A known-effects test begins with data whose correct answer is set in advance, then asks whether the software recovers it. Failure-case tests take a different approach: they feed the workflow malformed or risky inputs and check whether the problem is caught, rejected, or clearly documented.
What Belongs in a Replication Bundle
A useful bundle lets another researcher follow the study from fielded responses to reported estimates. Include the raw export, cleaned analysis file, codebook, methods notes, scripts, exclusions, and enough version information to identify the survey that respondents actually completed.
Replication Still Requires Privacy Judgment
Transparency does not mean publishing identifiable or sensitive records. Review respondent identifiers, URL parameters, open-text fields, retention plans, and file access before sharing a bundle, and provide only the materials that can be released responsibly.
FAQ
Do synthetic respondents use an LLM?
No. These validation and path checks use deterministic rules, known effects, fixed random seeds, and local scoring code. That makes the expected result reproducible rather than dependent on a model's changing output.
What should be in a replication bundle?
Include the raw export, cleaned analysis data, codebook, methods text, exclusion rules, design summary, and scripts needed to reproduce the reported estimates. Remove or protect fields that cannot be shared ethically.
