Hypothesis vs. Hypotheses — What's the Difference?
By Fiza Rafique & Urooj Arif — Updated on February 23, 2024
A hypothesis is a single proposed explanation for a phenomenon, based on limited evidence. Hypotheses are the plural form, indicating multiple such explanations.

Key Differences
A hypothesis is formulated as a singular statement that can be tested through experimentation or observation. It is often a starting point for scientific research, proposing a possible explanation for a specific phenomenon based on preliminary evidence. Hypotheses aim to be succinct and testable, offering a foundation for further investigation.
Hypotheses, on the other hand, refer to multiple propositions or suggested explanations for phenomena. This plurality is essential in scientific studies where multiple potential explanations for a single phenomenon are considered. Each hypothesis within the hypotheses set is subject to validation or refutation through empirical evidence.
The formulation of a hypothesis is a critical step in the scientific method, allowing researchers to create a focused question that guides their investigation. It typically predicts a relationship between two variables, setting the stage for testing and analysis.
The development of multiple hypotheses enables a more comprehensive exploration of a phenomenon. By considering various possible explanations, scientists can approach their research from multiple angles, increasing the robustness of their findings.
The evaluation of a hypothesis involves collecting data and conducting experiments to test its validity. This process is crucial for advancing scientific knowledge, as it determines whether the proposed explanation holds under scrutiny.

Evaluating hypotheses involves a similar process but on a larger scale. Researchers must design studies that can simultaneously or sequentially test multiple explanations, requiring more complex experimental designs and analytical techniques.

Hypothesis
A hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it.
Hypotheses
A tentative explanation for an observation, phenomenon, or scientific problem that can be tested by further investigation.

Hypothesis
(general) An assumption taken to be true for the purpose of argument or investigation.
Hypothesis
A tentative theory or supposition provisionally adopted to explain certain facts, and to guide in the investigation of others; hence, frequently called a working hypothesis.
Common Curiosities
What are hypotheses?
Hypotheses are multiple proposed explanations for various phenomena, intended for testing and analysis.
How is a hypothesis tested?
A hypothesis is tested through experiments or observations that seek to confirm or refute its predictions.
How do hypotheses contribute to scientific knowledge?
Hypotheses contribute by offering testable predictions that, when investigated, can advance our understanding of the natural world.
What happens if a hypothesis is refuted?
If refuted, the hypothesis is either revised or discarded, and new hypotheses may be developed based on the findings.
Why are multiple hypotheses important in research?
Multiple hypotheses allow for a comprehensive exploration of a phenomenon from different angles, enhancing the robustness of findings.
What is a hypothesis?
A hypothesis is a proposed explanation for a phenomenon, made as a starting point for further investigation.
Can a hypothesis be proven?
A hypothesis can be supported or refuted by evidence but is generally not considered to be definitively proven due to the possibility of future evidence contradicting the findings.
Do all scientific studies test a hypothesis?
Not all studies explicitly test a hypothesis; some may be exploratory in nature without a specific predictive statement.
Can there be more than one hypothesis in a study?
Yes, studies often include multiple hypotheses to explore different aspects of a phenomenon or to test various explanations.
How are hypotheses formulated?
Hypotheses are formulated based on observations, previous research, or theories, aiming to propose testable relationships between variables.
How are hypotheses evaluated?
Hypotheses are evaluated through the collection and analysis of data, using statistical methods to determine the likelihood that the observed outcomes support the predictions.
What distinguishes a hypothesis from a theory?
A hypothesis is a tentative explanation, while a theory is a well-substantiated explanation of some aspect of the natural world, based on a body of evidence.
Is it necessary to have a hypothesis before conducting an experiment?
While not always necessary, having a hypothesis often helps to focus the research and guide the experimental design.
Can a hypothesis be changed?
Yes, a hypothesis can be modified or refined based on preliminary data or in response to new evidence.
What role do hypotheses play in the scientific method?
Hypotheses are central to the scientific method, providing a basis for conducting experiments and testing predictions.
