What is a Hypothesis? One of the most common terms used in science classes 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.
In summary, a fact is a tested and confirmed observation or measurement. A hypothesis is basically an educated guess, and the terms theory and law synonymously describe a thoroughly tested explanatory framework which has a high predictive power and explains facts.
What's the Difference Between a Fact, a Hypothesis, a Theory, and a Law in Science? Each word has a specific meaning and not interchangeable. You may have heard someone disparage evolution because it's "just a theory." Gravity, on the other hand, must be 100 percent real — it's a "law," after all.
A scientific theory or law represents a hypothesis (or group of related hypotheses) which has been confirmed through repeated testing, almost always conducted over a span of many years. Generally, a theory is an explanation for a set of related phenomena, like the theory of evolution or the big bang theory .
A scientific hypothesis is an inferred explanation of an observation or research finding; while more exploratory in nature than a theory, it is based on existing scientific knowledge. A scientific law is an expression of a mathematical or descriptive relationship observed in nature.
For one thing, it is never quite explained how a hypothesis turns into a theory or law and, consequently, the boundaries are blurry, and definitions tend vary with the speaker. And there is no consistency in usage across fields, I’ll give some examples in a minute.
What is the difference between a fact, a theory, a hypothesis, and a scientific law? Dr. Joe Hanson explains. Brought to you by GotScience.Org.
This paper discusses the relationships between the terms hypothesis, prediction, theory, and law. In so doing, it addresses some misconceptions found in the literature and suggests that the only interpretation of the term hypothesis needed is that of a causal hypothesis. A more valid depiction of
