An hypothesis (plural, hypotheses ) is a proposed explanation for a given set of facts or observations. It is a starting point for scientific enquiry: the hypothesis may be right, it may be wrong, but it allows a basis for further experiments that test the correctness of the hypothesis .
What explains a set of observations?
An hypothesis is a proposed explanation for a set of observations, a phenomenon. Scientific hypotheses must satisfy a defining criterion: that they be testable .
What is a possible explanation for a set of facts that can be tested by further investigation called Apex?
A hypothesis is a possible explanation for a set of observations or an answer to a scientific question. A hypothesis must be testable and measurable. This means that researchers must be able to carry out investi- gations and gather evidence that will either support or disprove the hypothesis.
What is possible explanation?
adjective [verb-link ADJECTIVE] If you say that it is possible that something is true or correct , you mean that although you do not know whether it is true or correct, you accept that it might be. [vagueness]

Medical definitions for hypothesis

Is a hypothesis a prediction?
defined as a proposed explanation (and for typically a puzzling observation). A hypothesis is not a prediction . Rather, a prediction is derived from a hypothesis. A causal hypothesis and a law are two different types of scientific knowledge, and a causal hypothesis cannot become a law.
What are the two observations?
The two categories of observations are quantitative and qualitative . Quantitative observations involve numeric data, such as a frequency count.
What do you gather to test a prediction?
Next, you must gather evidence to test your prediction. Evidence is any type of data that may either agree or disagree with a prediction, so it may either support or disprove a hypothesis. Evidence may be gathered by an experiment. Assume that you gather evidence by making more observations of moths with eyespots.
What is the first step in the scientific method?
The first step in the Scientific Method is to make objective observations . These observations are based on specific events that have already happened and can be verified by others as true or false. Step 2. Form a hypothesis.
What is another word for possible explanation?
Some common synonyms of explain are elucidate , explicate, expound, and interpret.
What is a possible explanation that can be tested?
1) hypothesis an educated guess about a possible solution to a mystery; a prediction or statement that can be tested; A reasonable or educated guess; what a scientist thinks will happen in an experiment.
What is a proposed explanation that can be tested?
In science, a hypothesis is a proposed explanation that can be tested through further experiments and observations. It’s a still-unproven idea that requires the collection of more data in order to confirm or reject it. A hypothesis is often considered the first step of the scientific method.
What is a tentative explanation?
A tentative explanation would be a theory that has not been tested completely . A theory makes predictions about what should happen. Scientific investigations begin with a hypothesis or prediction about what will happen based on the ideas contained in a theory.
Is a hypothesis A tentative explanation?
scientific hypothesis , an idea that proposes a tentative explanation about a phenomenon or a narrow set of phenomena observed in the natural world.
What is the steps in the scientific method?
Form a hypothesis , or testable explanation. Make a prediction based on the hypothesis. Test the prediction. Iterate: use the results to make new hypotheses or predictions.
