What is a valid scientific hypothesis?
this is the final or proven hypothesis
Was this answer useful?
Thanks for the feedback!
An hypothesis is an untested theory or conjecture, so when a hypothesis is tested and passes the test it becomes a proven theory, or possibly a law or reason or explanation. U…ntil then it is an as-yet-unproven possibility or probability. Just make certain that the facts are not twisted to 'prove' the hypothesis, and the results are confirmed by other experiments and experimenters. It is even better if it becomes accepted by those who didn't agree with the idea in the first place, but that is not always possible! -- However, a theory is not born from one tested hypothesis, but many. A theory is the result of multiple hypotheses that are said to be true through multiple experiments. Also, a theory may never be actually proven, but merely accepted as the most reasonable explanation. Since science is constantly changing, theories are constantly being formulated to explain things about ourselves or our surroundings.
Observing scientific experiments that in conclusion provide credit for the hypothesis.
A valid hypothesis is one that is testable and rejectable, can be proven true as well as verified without external evidence. It also needs to be accepted by public opinion….
tested 3 times or more
Not necessarily. Let's say that we're testing a new medicine to treat heart disease. We wish to compare it against the current standard of care, so we might have what we c…all a "research hypothesis" stated as a question with a specific, measurable goal: Does the new medicine reduce mortality when compared to current medicine?" We could just as easily say "improve symptoms" as "reduce mortality", its all about what the new medicine is expected to do. In statistical terms, there's a different approach stated as a null hypothesis, which is not a question but a simple statement that there is no difference between the new and current drugs, something like "There is no difference in mortality between new drug and old drug." We then perform statistical tests to see if a difference is present - if we can't find a difference, we conclude the drug is truly no different. If we DO see a difference, we then reject the null hypothesis in favor of an alternate hypothesis that there IS a difference.
never go here
A scientific hypothesis has to be testable.
it could be clear and consice ps. i hope this helps -jonesfisher
Sorry but your question doesn't make sense... You have to know what the hypothesis is to test if your question is valid.
when results from the experiments repeatedly fail to support the hypothesis.
Strictly speaking, hypothesis is the step BEFORE a theory. A full sequence of scientific inquiry looks something like this: 1) Observation. Something is noticed; 2) Descriptio…n. The effect is broken down into its components. 3) Conjecture. An idea is formed. 4) Hypothesis. A notion of what's causing what is formed. 5) Experiment. The hypothesis is tested; this is repeated until consistent results are obtained. 6) Theory. A more complex and testable version of the hypothesis is enunciated. 7) Additional experiments. A shorthand version of the foregoing is simply "Hypothesis testing." In CASUAL conversation, people are wont to say, "I've got a theory about that" when what they ought to say is, "I have a hypothesis" or "I have a conjecture." The easy use of "theory" consistently leads non-scientists to assume that scientifically-established facts are weakly supported. Listen to a Creation v. Evolution debate and somebody will surely say, "Evolution is only a theory."
A scientific hypothesis is an "educated guess" about a result or solution based on prior knowledge and observation. It is the first step in the scientific method. The hypothes…is must be something that can be supported or defended through experimentation or observation.
A scientific hypothesis must be testable and falsifiable in order for it to be valid.
