A theory is a well-affirmed explanation of natural phenomena, which is frequently validated through experimentation and observation. While the hypothesis is based on a little amount of data, the theory is based on a wide set of data. The hypothesis is an unproven statement; that can be tested. On the other hand, the theory is a scientifically tested and proven explanation of fact or event. Hypothesis relies on suggestions, prediction, possibility or projects whereas a theory is supported by evidence and is verified.
The hypothesis may or may not be proved true, so the result is uncertain. On the contrary, the theory is one, that is assumed to be true and so its result is certain. Hypothesis and theory are two levels of the scientific method, i. Leave a Reply Cancel reply Your email address will not be published.
An educated guess, based on certain data, as an inception for further research or investigation is called hypothesis. Word of the Day. Meanings Meanings. Previous What Are Context Clues? Next "Reeking" vs. What does theory mean? There are other uses of the word theory as well. What does hypothesis mean? How to use each Although theory in terms of science is used to express something based on extensive research and experimentation, typically in everyday life, theory is used more casually to express an educated guess.
For example: Her opinion is just a theory , of course. A theory will always remain a theory; a law will always remain a law.

Learning Objectives Describe the difference between hypothesis and theory as scientific terms. Describe the difference between a theory and scientific law.
What is a Fact? What is a Hypothesis? The word can have many different definitions, depending on the context in which it is being used: An educated guess: a scientific hypothesis provides a suggested solution based on evidence. Prediction: if you have ever carried out a science experiment, you probably made this type of hypothesis when you predicted the outcome of your experiment.
Tentative or proposed explanation: hypotheses can be suggestions about why something is observed. In order for it to be scientific, however, a scientist must be able to test the explanation to see if it works and if it is able to correctly predict what will happen in a situation. What is a Theory? The United States National Academy of Sciences describes what a theory is as follows: "Some scientific explanations are so well established that no new evidence is likely to alter them.
Note some key features of theories that are important to understand from this description: Theories are explanations of natural phenomena. They aren't predictions although we may use theories to make predictions. They are explanations as to why we observe something. Theories aren't likely to change.
Both theories and hypotheses are usually based on some date and can be tested. This means either could be substantiated or falsified. In common speech, people use theory and hypothesis as synonyms referring to something they speculate. A hypothesis is not as firm as a law, although a theory can be.
In the scientific method, a hypothesis comes before a theory because you need evidence to support a theory and that evidence typically comes from tests that start with hypotheses. Explore more commonly confused science terms like hypothesis vs.
