Chapter 1 - The nature of Science Study Guide An experiment is a suggested explanation for an observation. False (Hypothesis) The study of objects beyond Earth's atmosphere is ecology. FALSE (Astronomy) The water in the Earth's oceans, seas, lakes, rivers, glaciers, and in Earth's atmosphere makes up the hydrosphere.. TRUE. Astronomers study Earth, its neighbors, and other matter in the universe.

- Inference. 1  We draw inferences on the basis of observations, or on conclusions drawn from previous observations. 2  Inference is the interpretation of facts. (A statement of fact is an observation statement that can be verified by the use of the senses.) 3  Valid inferences are based on sufficient and relevant evidence.

Which of These Statements Is True Regarding Scientific Theories? A hypothesis is a question or an idea that a scientist tries to answer by performing an experiment. If the data derived from the experiment is compelling enough, the hypothesis becomes a theory. Scientists accept theories as adequate explanations for phenomena. This is in stark contrast to the use of the word theory in a non-scientific sense.

Forming a Good Hypothesis for Scientific Research Forming a Hypothesis. The first step of a psychological investigation is to identify an area of interest and develop a hypothesis that can then be tested. While a hypothesis is often described as a hunch or a guess, it is actually much more specific. A hypothesis can be defined as an educated guess about the relationship between two or more variables. For example, a researcher might be interested in the relationship between study habits and test anxiety.

- A theory (hypothesis) is a question, and science (scientific) is what is used to answer the question. Added: A theory is NOT a question, it is an general explanation for a … phenomenon, or a set of phenomena, and is internally consistent, falsifiable and supported by myriad line of converging evidence.

- A hypothesis is a statement of the expected results of your research. A hypothesis states your guess as to the cause and effect that you expect to find (how one variable will affect another variable). Variables are merely things that can change (vary). Hypotheses are typically (but not always) stated in IF-THEN form.

theory the·o·ry. A set of statements or principles devised to explain a group of facts or phenomena. Most theories that are accepted by scientists have been repeatedly tested by experiments and can be used to make predictions about natural phenomena.

What Are Examples of a Hypothesis? A hypothesis is an explanation for a set of observations. Here are examples of a scientific hypothesis. Answer: Although you could state a scientific hypothesis in various ways, most hypothesis are either If, then statements or else forms of the null hypothesis. The null hypothesis sometimes is called the no difference hypothesis. The null hypothesis is good for experimentation because it's simple to disprove. If you disprove a null hypothesis, that is evidence for a relationship between the variables you are examining.

Theory formulation A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment.he theory of biological evolution is more than just a theory.. It is as factual an explanation of the universe as the atomic theory of matter or the germ theory of disease. Our understanding of gravity is still a work in progress.

What is the difference between a theory and a hypothesis, in scientific terms? A hypothesis is an attempt to explain phenomena. It is a proposal, a guess used to understand and/or predict something. A theory is the result of testing a hypothesis and developing an explanation that is assumed to be true about something. A theory replaces the hypothesis after testing confirms the hypothesis, or the hypothesis is modified and tested again, until predictable results occur.

unit-1 Nature and scope of science The essence of science is validation by observation. But it is not enough for scientific theories to fit only the observations that are already known. Theories should also fit additional observations that were not used in formulating the theories in the first place; that is, theories should have predictive power.

Occam's razor As a logical principle, Occam's razor would demand that scientists accept the simplest possible theoretical explanation for existing data. However, science has shown repeatedly that future data often support more complex theories than do existing data.

Hypothesis What is a Hypothesis? A hypothesis is a tentative, testable answer to a scientific question. Once a scientist has a scientific question she is interested in, the scientist reads up to find out what is already known on the topic. Then she uses that information to form a tentative answer to her scientific question.

Hypothesis Sometimes people refer to the tentative answer as an educated guess.. Keep in mind, though, that the hypothesis also has to be testable since the next step is to do an experiment to determine whether or not the hypothesis is right! A hypothesis leads to one or more predictions that can be tested by experimenting.

How is the meaning of theory in science different from the the everyday use of the term? Theory in science: A well tested explanation that unifies a broad range of observations and hypotheses, and enables scientists to make accurate predictions about new situations. Theory everyday term: An idea used to account for a situation or justify a course of action.

- If that theory is later found to have a counter-example it is modified (hypothesis -> theory - same process) or a completely new hypothesis proposed and tested. The hypothesis alwasy comes before the theory. it is a practical explanation that the scientist develops that accounts for a theory.

- To a layman such as I am, my question should perhaps have been this: meteorology produces 'best guesses' or probable predictions. ... Mathematics, for example, gives the product of two plus two as four; no approximates, no probables, but a definite outcome. This, to me, is a science.

Biology Lab- Scientific Method This is the testable statement. It must be possible to falsify this statement. The statement should involve the dependent variable and be in the form of a prediction. Also stated as null hypothesis. NULL because the prediction is generally that nothing will happen as a result of the experimental treatment.

- A falsifiable hypothesis is a proposed explanation for an event or occurrence that can be proven false. The falsifiability of a hypothesis requires that the statement can be refuted based on a scientific and observable investigation. Continue Reading.

What Is a Scientific Theory? In the scientific method, there is a clear distinction between facts, which can be observed and/or measured, and theories, which are scientists’ explanations and interpretations of the facts. An important part of scientific theory includes statements that have observational consequences.f enough evidence accumulates to support a hypothesis, it moves to the next step — known as a theory — in the scientific method and becomes accepted as a valid explanation of a phenomenon. Tanner further explained that a scientific theory is the framework for observations and facts.
