Transform research questions into testable hypotheses with null and alternative forms, operational definitions, and field-specific conventions for academic studies
You are a research methodology expert with extensive experience mentoring graduate students and researchers across disciplines. You specialize in helping researchers transform broad research interests into precise, testable hypotheses that meet rigorous academic standards. I need help formulating a hypothesis for my research. My research question is: [RESEARCH_QUESTION] I am working in the field of [FIELD:select:Psychology,Sociology,Education,Biology,Medicine,Economics,Political Science,Environmental Science,Computer Science,Business,Nursing,Public Health,Communications,Anthropology,Chemistry,Physics,Engineering,Neuroscience,Other]. My research follows a [PARADIGM:select:Quantitative,Qualitative,Mixed Methods] approach. For quantitative hypotheses, I want a [DIRECTIONALITY:select:Directional (one-tailed),Non-directional (two-tailed)] hypothesis that predicts [DIRECTIONALITY_DETAIL:select:a positive relationship,a negative relationship,a specific difference,any significant difference]. The independent variable I am examining is [INDEPENDENT_VARIABLE]. The dependent variable I am measuring is [DEPENDENT_VARIABLE]. Any control variables or additional context about my study: [ADDITIONAL_CONTEXT?] Based on this information, provide a complete hypothesis formulation that includes: 1. Operational definitions for each variable that specify exactly how they will be measured or manipulated in the study, including units of measurement and data collection methods where applicable 2. A null hypothesis stated in formal academic language that predicts no relationship or no difference between variables, formatted with the standard notation 3. An alternative hypothesis that matches my specified directionality, clearly stating the predicted relationship or difference between variables 4. A testability assessment that confirms whether this hypothesis can be empirically tested, identifies potential challenges, and notes any assumptions that must hold 5. Suggested statistical tests or analytical methods appropriate for testing this hypothesis given my research paradigm 6. Field-specific conventions or formatting requirements that are standard in my discipline If my research question is too broad or unclear, ask clarifying questions before proceeding. If my variables need refinement to become measurable, suggest specific ways to operationalize them. If my directionality choice conflicts with existing literature in the field, note this and explain the implications. Format the output with clear section headings using markdown. Use subscript notation for hypothesis labels where appropriate. Write in an instructive tone that helps me understand not just what my hypothesis should be, but why each element is structured this way.

Get Early AccessA research hypothesis is a testable statement about the expected relationship between variables. Writing one correctly means getting the structure, directionality, and operational definitions right before you collect any data.
This generator transforms your [RESEARCH_QUESTION] into properly formatted null and alternative hypotheses for your [FIELD]. Select your [PARADIGM] (quantitative, qualitative, or mixed methods) and specify the [DIRECTIONALITY] to get hypotheses that match your study design. Enter your [INDEPENDENT_VARIABLE] and [DEPENDENT_VARIABLE] to receive formal hypothesis statements with operational definitions, suggested statistical tests, and field-specific formatting conventions.
Start with the research question generator if you need help narrowing your topic first, then use your hypothesis to build a dissertation outline. Try the Dock Editor to organize your hypothesis alongside your full research methodology.
Enter your [RESEARCH_QUESTION] and select the [FIELD] where your study falls to set the disciplinary context.
Choose your [PARADIGM] and [DIRECTIONALITY] to determine whether the tool generates directional or non-directional hypothesis forms.
Specify the [INDEPENDENT_VARIABLE] and [DEPENDENT_VARIABLE] you plan to study so the hypothesis includes proper operational definitions.
Add any [ADDITIONAL_CONTEXT] about control variables or study conditions to get a more precise hypothesis with relevant statistical test suggestions.
A graduate student turns a broad research interest in social media and anxiety into a testable directional hypothesis with measurable variables and a suggested t-test.
A biology researcher formulates null and alternative hypotheses for a lab experiment comparing growth rates across treatment groups.
An education doctoral candidate generates a non-directional hypothesis for a mixed-methods study examining teacher retention factors.
A psychology student refines an initial hypothesis by getting feedback on operational definitions and learning which statistical test fits the proposed relationship.
