Key points at a glance
- A hypothesis is a reasoned expectation that can be investigated.
- Specify the variables, population and expected relationship.
- An unsupported hypothesis does not make the thesis unsuccessful.
Distinguish the question from the expected answer
A research question states what you want to find out. A hypothesis proposes a provisional answer that an appropriate study can examine. “How are commuting time and library visits related?” might lead to a reasoned expectation about the direction of that relationship.
Not every thesis needs hypotheses specified in advance. An exploratory qualitative study may be organised around open research questions. Use the approach that fits your aim rather than adding hypotheses because they appear more scientific.
Build the statement from a theoretical argument
Explain why you expect the relationship before writing the hypothesis itself. Identify the theory or earlier evidence supporting the expectation. A personal impression may start your reading, but it cannot replace the academic rationale.
An original illustrative statement is: “Among the students studied, longer one-way commuting time is associated with fewer library visits per week.” It identifies two variables and a direction. It does not present a finding or establish a causal effect.
Separate associations, group differences and causes
An association hypothesis connects variables; a difference hypothesis compares groups. Another fictional example is: “Students with and without access to a quiet workspace differ in their reported concentration.” Without a justified prediction about which group scores higher, this is a non-directional expectation.
A causal interpretation needs a design and assumptions that support it. A one-time survey of commuting and library visits cannot by itself show that commuting changes attendance. Employment or housing circumstances might also matter.
Check whether each concept can be measured. What counts as a visit, and which week or month should participants consider? These operational decisions must be clear before data collection, not improvised after you inspect the responses.
Keep testing and reporting transparent
Record planned hypotheses and analysis decisions before you know the results. Additional questions may emerge later, but identify those analyses as exploratory. Do not quietly rewrite an original expectation to make it appear that you predicted the observed pattern.
Describe the result with the uncertainty appropriate to your method. “The data did not support H1” is often more defensible than claiming a final disproof. A statistically non-significant result does not establish equality or prove that no relationship exists. Use the methods literature relevant to your actual analysis.
Final submission context
Formal details can feel like a separate writing task, but they matter just as much for a printed submission. Anything missing, misplaced or inconsistently formatted in the document will also appear in the bound copy.
Use this guide together with your cover page, table of contents, page numbers, source notes and appendices. Prepare the final PDF for printing and binding only after the complete file has been checked.
Practical check before PDF export
- Do headings, chapter structure and page numbers match?
- Are sources, figures and tables included completely?
- Are required elements such as declarations, appendices or the cover page included where required?
- Did you open and check the final PDF after exporting it?
Checklist
- Each hypothesis has an academic rationale.
- The concepts and population are clear.
- The variables can be measured.
- The design supports the type of conclusion claimed.
- Planned and exploratory analyses are identified.
Common mistakes
- Turning a question into an unsupported assertion.
- Treating an association as a cause.
- Changing hypotheses after seeing the results without disclosure.

Frequently asked questions
How many hypotheses should I have?
Use the number you can justify from your question and investigate properly with your design. There is no universal minimum.
Can a hypothesis be non-directional?
Yes, if existing theory and evidence do not justify a direction. The choice should fit the question and planned analysis.
Is an unsupported hypothesis a bad result?
No. A transparent investigation and a careful interpretation matter more than confirming your expectation. Report unexpected results honestly.
