Frequently Asked Questions
What is the difference between null and alternative hypotheses?
The null hypothesis (H₀) states there is no effect, difference, or relationship between variables - it represents the status quo or default assumption. The alternative hypothesis (H₁ or Hₐ) contradicts the null and states there IS an effect, difference, or relationship. In hypothesis testing, we collect data to determine whether we have sufficient evidence to reject the null hypothesis in favor of the alternative.
Should I use a one-tailed or two-tailed hypothesis?
Use a two-tailed hypothesis when you predict a difference exists but do not specify the direction (e.g., "Group A and B differ"). Use a one-tailed (directional) hypothesis when you predict the specific direction of the effect (e.g., "Group A scores higher than Group B"). Two-tailed tests are more conservative and commonly preferred unless you have strong theoretical justification for predicting direction.
How do I write a good research hypothesis?
A good hypothesis is: (1) testable and falsifiable, (2) specific about variables and their expected relationship, (3) grounded in existing theory or research, (4) measurable with clear operational definitions, and (5) stated before data collection. This tool guides you through these elements to create properly formatted null and alternative hypotheses appropriate for your research design.
Is this hypothesis generator free to use?
Yes, completely free with no registration required. Generate unlimited hypotheses for all your research projects, assignments, proposals, and dissertations. Export your hypotheses with AI analysis prompts for further development.
Can this tool help me with my dissertation hypotheses?
Absolutely. This tool is designed specifically for graduate-level research. It helps you formulate testable hypotheses that align with your research questions, methodology, and statistical analysis plans - all critical components of your dissertation proposal and methodology chapter.
