For example: her working hypothesis is that this new drug also has an unintended effect on the heart, and she is curious what the clinical trials will show. Synonyms for hypothesis include: assumption , conclusion , conjecture , guess , inference , premise , theorem , and thesis.
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. So in casual language, theory and hypothesis are more likely to be used interchangeably to express an idea or speculation. In most everyday uses, theory and hypothesis convey the same meaning.
For example:. It is based on tested results that support or substantiate it, whereas a hypothesis is formed before the research. Miller, a cell biologist at Brown University. It not only explains those facts, but predicts what you ought to find from other observations and experiments. So remember, first comes a hypothesis , then comes theory. Find out the correct spelling here! Feedback We've Added New Words! Beliefs may or may not be incorrect; they just are outside the realm of science to explore.
A common misconception is that scientific theories are rudimentary ideas that will eventually graduate into scientific laws when enough data and evidence has accumulated. A theory does not change into a scientific law with the accumulation of new or better evidence. Remember, theories are explanations and laws are patterns we see in large amounts of data, frequently written as an equation. 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. They have a large amount of support and are able to satisfactorily explain numerous observations.
That's just not how science works. Logical deductions based on axioms can be proven, but not scientific hypotheses.
On top of that I find it somewhat strange to claim that a theory doesn't have to be testable, if it's built up from hypotheses, which DO have to be testable Comparison chart Differences — Similarities —.
