What is a research hypothesis?
It is a testable assumption about a relationship, behavior, preference, or outcome that can be checked with survey data.

Why does it include H0?
The null hypothesis gives you a baseline of no meaningful difference or effect, so the test has something concrete to reject.

How do I test a hypothesis with a survey?
Use the generated questions, define the target segment and metric, collect enough responses, then compare results against the expected threshold.

How many hypotheses should I test at once?
Usually a small set works best. Prioritize the assumptions that would change a product, marketing, program, or operational decision.

Do I need an account to use this tool?
No. The tool can generate a draft on this page. To save surveys, collect responses, and manage projects, use a SurveyNinja account.

Can I edit the result?
Yes. Treat AI output as a practical first draft. You can rewrite, remove, reorder, or expand it before launch.

Which languages are supported?
English, Spanish, and Portuguese are supported by the AI endpoints. The current locale is used when possible.

Can I continue in another AI tool?
Yes. Start with a plan, questions, personas, or hypotheses, then move to improvement or response summary when the workflow changes.

Are my prompts and responses sensitive?
Avoid pasting personal data, private identifiers, or confidential respondent details into public AI tools unless you have the right basis to process them.

Are there usage limits?
Yes. Public AI endpoints use rate limits so the tools stay responsive. Workspace and team limits depend on the configured plan.
