A hypothesis is a tentative explanation that can be tested by further investigation. A theory is a well-supported explanation of observations. A scientific law is a statement that summarizes the relationship between variables. An experiment is a controlled method of testing a hypothesis.

A hypothesis (plural hypotheses) is a proposed explanation for an observation. The definition depends on the subject. In science, a hypothesis is part of the scientific method. It is a prediction or explanation that is tested by an experiment. Observations and experiments may disprove a scientific hypothesis, but can never entirely prove one.

A hypothesis is an educated guess, based on observation. It's a prediction of cause and effect. Usually, a hypothesis can be supported or refuted through experimentation or more observation. A hypothesis can be disproven but not proven to be true. Example: If you see no difference in the cleaning ability of various laundry detergents, you might ...

hypothesis. science. scientific hypothesis, an idea that proposes a tentative explanation about a phenomenon or a narrow set of phenomena observed in the natural world. The two primary features of a scientific hypothesis are falsifiability and testability, which are reflected in an "If…then" statement summarizing the idea and in the ...

A hypothesis proposes a relationship between the independent and dependent variable. A hypothesis is a prediction of the outcome of a test. It forms the basis for designing an experiment in the scientific method.A good hypothesis is testable, meaning it makes a prediction you can check with observation or experimentation.

A scientific hypothesis is a tentative, testable explanation for a phenomenon in the natural world. It's the initial building block in the scientific method. Many describe it as an "educated guess ...

What is ( − 4.00 × 1011)4? The scientific method is a method of scientific inquiry that is thorough and systematic. Such inquiries must have a specific hypothesis, experimental testing, and conclusions.

5. Phrase your hypothesis in three ways. To identify the variables, you can write a simple prediction in if…then form. The first part of the sentence states the independent variable and the second part states the dependent variable. If a first-year student starts attending more lectures, then their exam scores will improve.

By Anne Marie Helmenstine, Ph.D. Alternate Spellings: plural: hypotheses. Examples: Upon observing that a lake appears blue under a blue sky, you might ...

Hypothesis: A hypothesis is a statement used to guide researches or experiments. Also, a statement that provides a proposed explanation for an observation. A hypothesis must be testable and ...

A hypothesis is an idea about how something works that can be tested using experiments. A prediction says what will happen in an experiment if the hypothesis is correct. Presenter 1: We are going ...

A hypothesis (pl.: hypotheses) is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories.

A hypothesis is a possible explanation that can be tested. This simple definition needs some further explanation. It says it must have a possible explanation. The hypothesis should apply reasoning ...

scientific method, mathematical and experimental technique employed in the sciences. More specifically, it is the technique used in the construction and testing of a scientific hypothesis. The process of observing, asking questions, and seeking answers through tests and experiments is not unique to any one field of science.

hypothesis, something supposed or taken for granted, with the object of following out its consequences (Greek hypothesis, "a putting under," the Latin equivalent being suppositio ). Discussion with Kara Rogers of how the scientific model is used to test a hypothesis or represent a theory. Kara Rogers, senior biomedical sciences editor of ...

Examples of Null Hypotheses. Hyperactivity is unrelated to eating sugar. All daisies have the same number of petals. The number of pets in a household is unrelated to the number of people living in it. A person's preference for a shirt is unrelated to its color.

A scientific hypothesis must be testable. A scientific hypothesis must be falsifiable. A Scientific Hypothesis Must Be Testable. For a hypothesis to be testable means that it is possible to make observations that agree or disagree with it. If a hypothesis cannot be tested by making observations, it is not scientific. Consider this statement:

hypothesis: [noun] an assumption or concession made for the sake of argument. an interpretation of a practical situation or condition taken as the ground for action.

Functions of Hypothesis. Following are the functions performed by the hypothesis: Hypothesis helps in making an observation and experiments possible. It becomes the start point for the investigation. Hypothesis helps in verifying the observations. It helps in directing the inquiries in the right direction.

Scientific Hypothesis Examples . Hypothesis: All forks have three tines. This would be disproven if you find any fork with a different number of tines. Hypothesis: There is no relationship between smoking and lung cancer.While it is difficult to establish cause and effect in health issues, you can apply statistics to data to discredit or support this hypothesis.

Answer link. "A tentative conclusion based on given evidence..." See this old answer. And see this old answer. In the hierarchy of scientific explanation, an hypothesis can become ("graduate to" if you like) a theory if it can be applied and adapted to a variety of scientific phenomena, and TESTED under different conditions, and circumstances...
