Hypothesis vs. Prediction — What's the Difference?
By Urooj Arif & Fiza Rafique — Updated on May 13, 2024
Hypotheses are educated guesses based on prior knowledge and theory, used in scientific methods; predictions are specific forecasts about future outcomes, often based on hypotheses or patterns.

Key Differences
A hypothesis is an educated guess formed as a statement that can be tested scientifically, typically arising from background research and existing theories. In contrast, a prediction is a specific statement about what will happen in the future under certain conditions, often derived from a hypothesis.
Hypotheses are crucial for experiments as they provide a basis for formulating the experimental design and methodology, whereas predictions are often used to test the accuracy of the hypothesis in specific scenarios.
In scientific research, hypotheses must be testable and falsifiable, which means they can be proven false through experimentation. Predictions, on the other hand, do not necessarily require a testable format but must be measurable and observable.
Hypotheses generally require a deeper understanding of the subject area, as they are grounded in theoretical frameworks. Predictions can be simpler and are sometimes made with less comprehensive knowledge, relying more on observational data or previous patterns.
While hypotheses can lead to the development of new theories if they are repeatedly validated, predictions typically serve to confirm or refine existing hypotheses without necessarily contributing to theoretical advancements.

A forecast about future outcomes based on patterns.
Role in Science
Forms the basis of scientific experiments.
Used to test the outcomes of an experiment.
Requirement
Must be testable and falsifiable.
Should be measurable and observable.

Compare with Definitions
Hypothesis
A tentative insight into the natural world.
The hypothesis of water memory challenges traditional scientific understanding.
Prediction
A statement forecasting a specific outcome.
His prediction that the stock market would crash proved accurate.
Hypothesis
A theoretical framework for further investigation.
Her hypothesis involves the role of genetics in personality development.
Prediction
An assumption made before testing or occurrence.
The prediction was that the vaccine would be 90% effective.
Hypothesis
A statement to be tested by scientific research.
The hypothesis was that lower temperatures would slow bacterial growth.
Prediction
A conjecture about future events.
Her prediction is that remote work will become more common.
Hypothesis
A foundation for experimental design.
The experiment was designed around the hypothesis that sleep improves memory.
Prediction
An expectation based on past data or trends.
Based on weather patterns, the prediction for rain this weekend seems likely.
Hypothesis
A proposed explanation for a phenomenon.
The hypothesis that increased sunlight boosts plant growth is under investigation.
Prediction
A speculative forecast about potential results.
The prediction of a tech breakthrough in five years sparked investor interest.
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.
Prediction
A prediction (Latin præ-, "before," and dicere, "to say"), or forecast, is a statement about a future event. They are often, but not always, based upon experience or knowledge.
Hypothesis
A tentative explanation for an observation, phenomenon, or scientific problem that can be tested by further investigation.
Prediction
The act of predicting.
Hypothesis
Something taken to be true for the purpose of argument or investigation; an assumption.
Prediction
Something foretold or predicted; a prophecy.
Hypothesis
The antecedent of a conditional statement.
Prediction
A statement of what will happen in the future.
Hypothesis
(sciences) Used loosely, a tentative conjecture explaining an observation, phenomenon or scientific problem that can be tested by further observation, investigation and/or experimentation. As a scientific term of art, see the attached quotation. Compare to theory, and quotation given there.
Prediction
(statistics) A probability estimation based on statistical methods.
Hypothesis
(general) An assumption taken to be true for the purpose of argument or investigation.
Prediction
The act of foretelling; also, that which is foretold; prophecy.
The predictions of cold and long winters.
Hypothesis
(grammar) The antecedent of a conditional statement.
Prediction
The act of predicting (as by reasoning about the future)
Hypothesis
A supposition; a proposition or principle which is supposed or taken for granted, in order to draw a conclusion or inference for proof of the point in question; something not proved, but assumed for the purpose of argument, or to account for a fact or an occurrence; as, the hypothesis that head winds detain an overdue steamer.
An hypothesis being a mere supposition, there are no other limits to hypotheses than those of the human imagination.
Prediction
A statement made about the future
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.
Hypothesis
A proposal intended to explain certain facts or observations
Hypothesis
A tentative theory about the natural world; a concept that is not yet verified but that if true would explain certain facts or phenomena;
A scientific hypothesis that survives experimental testing becomes a scientific theory
He proposed a fresh theory of alkalis that later was accepted in chemical practices
Hypothesis
A message expressing an opinion based on incomplete evidence
Common Curiosities
What is a hypothesis?
A hypothesis is an educated guess or proposition that attempts to explain certain phenomena or relationships in a testable and falsifiable manner.
What makes a good hypothesis?
A good hypothesis is clear, testable, based on existing knowledge, and falsifiable, meaning it can be proven wrong.
What is a prediction?
A prediction is a specific statement or guess about what will happen in the future based on past data, observation, or theory.
What is the difference between a hypothesis and a theory?
A hypothesis is a tentative explanation that can be tested and falsified, while a theory is a well-substantiated explanation of some aspect of the natural world, backed by consistently confirmed research and evidence.
How do predictions differ from hypotheses?
Predictions are often derived from hypotheses and focus on specific outcomes, while hypotheses propose broader explanations needing testing.
Why are predictions important?
Predictions help in testing the validity of hypotheses and are crucial in planning and adjusting strategies in various fields.
How do hypotheses impact scientific conclusions?
Hypotheses are critical as they form the foundation upon which scientific conclusions are drawn, influencing how experiments are structured and interpreted.
Can a hypothesis be proven true?
In science, a hypothesis can be supported or corroborated but not proven true absolutely, as further testing might contradict it.
What role do predictions play in daily life?
In daily life, predictions can help in planning, decision making, and risk assessment, such as predicting weather or economic conditions.
How are hypotheses used in scientific research?
Hypotheses guide the design and direction of experiments, helping researchers to systematically test and refine scientific theories.
Can predictions be inaccurate?
Yes, predictions can be inaccurate if based on faulty data, incorrect assumptions, or when unexpected variables interfere.
How can one test a prediction?
A prediction can be tested through experiments, data collection, and analysis, checking whether the actual outcomes align with the predicted ones.
What happens if a hypothesis is falsified?
If a hypothesis is falsified, it is either revised or rejected, which is a normal part of the scientific process, helping to refine or discard unsupported theories.
Are all predictions based on hypotheses?
Not all predictions are based on hypotheses; some are based purely on statistical data analysis or past patterns without a theoretical framework.
How does one formulate a hypothesis?
A hypothesis is formulated based on observations, existing literature, and sometimes speculative insight, aiming to be as specific and testable as possible.
