Why do theories have greater certainty than hypothesis?

A theory is based on substantiated data, repeated testing, and the consensus of a wide group of scientists/researchers. But, because theory is a result of scientifically rigorous research, it is more likely that the theory is true (as compared to a single hypothesis).

What is an explanation that always applies under the same circumstances?

A scientific theory summarizes a hypothesis or group of hypotheses that have been supported with repeated testing.

Why is it important to follow the scientific method in order?

The scientific method attempts to minimize the influence of bias or prejudice in the experimenter. That’s the job of the scientific method. It provides an objective, standardized approach to conducting experiments and, in doing so, improves their results.

Why is it important for a hypothesis to be falsifiable?

Falsifiability is the capacity for some proposition, statement, theory or hypothesis to be proven wrong. That capacity is an essential component of the scientific method and hypothesis testing. The requirement of falsifiability means that conclusions cannot be drawn from simple observation of a particular phenomenon.

How are hypotheses and theories similar How do they differ?

A hypothesis proposes a tentative explanation or prediction. A scientist bases their hypothesis on a specific observed event, making an educated guess as to how or why that event occurs. A theory, on the other hand, is a substantiated explanation for an occurrence.

How are hypotheses formulated?

A hypothesis can be formulated in two ways: deductive and inductive hypothesis building. Deductive hypothesis building starts with an established theory. A hypothesis is formulated based on theory propositions and used to test the theory.

Why scientific method is important in chemistry?

Chemists use the scientific method to perform experiments, pose hypotheses, and formulate laws and develop theories, so that they can better understand the behavior of the natural world.

Why is forming a hypothesis an important step in the scientific method?

Why is forming a hypothesis an important step in the scientific method? Cannot be scientifically validated. By stating a formal hypothesis, a scientist can adequately design the best control conditions for designing experiments intended to falsify the hypothesis.

Why is repeatability and reproducibility important in experiments?

Repeatability and reproducibility are ways of measuring precision, particularly in the fields of chemistry and engineering. In general, scientists perform the same experiment several times in order to confirm their findings. These findings may show variation.

Does a scientific hypothesis have to be falsifiable?

A hypothesis must also be falsifiable. That is, there must be a possible negative answer. For example, if I hypothesize that all green apples are sour, tasting one that is sweet will falsify the hypothesis. Note, however, that it is never possible to prove that a hypothesis is absolutely true.

How can we determine whether a fact is true or false?

We can determine whether it is true by researching the evidence. This may involve numbers, dates, testimony, etc. (Ex.: “World War II ended in 1945.”) The truth of the fact is beyond argument if one can assume that measuring devices or records or memories are correct. Facts provide crucial support for the assertion of an argument.

What is ex post facto research design?

Despite studying facts that have already occurred, ex post facto research shares with experimental research design some of its basic logic of inquiry. Ex post facto research design Looks like you do not have access to this content. Don’t know how to login? between raters.

What is the difference between a fact and a fact beyond argument?

A fact is verifiable. We can determine whether it is true by researching the evidence. This may involve numbers, dates, testimony, etc. (Ex.: “World War II ended in 1945.”) The truth of the fact is beyond argument if one can assume that measuring devices or records or memories are correct.

What is the difference between a fact and an opinion?

Facts provide crucial support for the assertion of an argument. However, facts by themselves are worthless unless we put them in context, draw conclusions, and, thus, give them meaning. An opinion is a judgment based on facts, an honest attempt to draw a reasonable conclusion from factual evidence.
