如何使用 假设生成器
- Describe the research topic and the relationship you suspect exists between variables.
- List any variables you've already identified — or leave it for the AI to suggest them.
- Select the hypothesis type that matches your research design.
- Choose 3-5 pairs to explore different angles on your research topic.
- Add a theoretical framework if you have one — it strengthens the hypothesis justification.
使用案例
Develop hypotheses for a thesis or dissertation research proposal
Generate null and alternative hypothesis pairs for statistical testing
Explore multiple testable predictions before committing to a study design
Create hypotheses for a grant proposal's research design section
最佳结果的技巧
- Always generate both null and alternative hypotheses — you need both for proper statistical testing.
- The theoretical justification is what reviewers and committees care about most — ensure it's grounded in established theory.
- Use the suggested statistical test to plan your analysis before collecting data.
- If you can't operationalize (measure) a variable, the hypothesis isn't testable yet — refine it.
- Run the tool with 5 pairs, then narrow down to the 1-2 most feasible and original hypotheses.
常见问题
What's the difference between null and alternative hypotheses?
The null hypothesis (H0) states there is NO significant effect or relationship. The alternative hypothesis (H1) states there IS a significant effect. You test the null and either reject it (supporting H1) or fail to reject it. Both must be stated.
Should I use directional or non-directional hypotheses?
Use directional (one-tailed) when theory or prior research suggests a specific direction of the effect (X increases Y). Use non-directional (two-tailed) when you expect a relationship but aren't sure of the direction. Non-directional is more conservative.
How many hypotheses should my study have?
Most studies have 1-3 main hypotheses. Each hypothesis should map to a specific research question. Too many hypotheses increases the risk of Type I errors and makes the study unfocused.
Do I need a theoretical framework?
For graduate-level research, yes. A theoretical framework explains WHY you expect the relationship in your hypothesis. It moves your study from 'I wonder if...' to 'Based on [theory], we predict that...'
Can I use this for qualitative research?
Qualitative research typically uses research questions rather than hypotheses. However, some qualitative approaches (grounded theory, mixed methods) may use working hypotheses. Select 'non-directional' for exploratory qualitative predictions.
