1.3: Hypothesis, Theories, and Laws

The primary tool, in the research process, is a hypothesis, that intends to suggest new experiments and observations. There are many experiments which are undertaken with the sole objective of testing hypothesis.

It refers to a supposition, regarding an observable phenomenon of a relationship between various phenomena. Both hypothesis and theory are important components of developing an approach, but these are not same. There exist a fine line of difference between hypothesis and theory, discussed in this article, have a look.

Basis for Comparison Hypothesis Theory Meaning An educated guess, based on certain data, as an inception for further research or investigation is called hypothesis. Theory is a well substantiated explanation of natural phenomena, which is continuously validated through experimentation and observation.

It is scientifically tested and proven. Relies on Projection or possibility. Evidence and verification. Result Uncertain Certain Relationship Outcome of theory. Formulated through hypothesis. An unproven statement or a mere assumption to be proved or disproved, about a factor, on which the researcher is interested, is called a hypothesis. It is a tentative statement, which is concerned with the relationship between two or more phenomena, as specified by the theoretical framework.

The hypothesis has to go through a test, to determine its validity. In other words, the hypothesis is a predictive statement, which can be objectively verified and tested through scientific methods, and relates the independent factor to the dependent one.

To a researcher, a hypothesis is more like a question which he intends to resolve. The salient features of hypothesis are:. An idea or a broad range of ideas that are assumed to be true, which aims at explaining cause and effect relationship between multiple observed phenomena.

It is based on hypothesis, which after a thorough analysis and continuous testing and confirmation through observation and experiments, becomes a theory. As it is backed by evidence, it is scientifically proven. Just like hypothesis, theories can also be accepted or rejected.

As more and more information is gathered on the subject, theories are modified accordingly, to increase the accuracy of prediction over time. The points given below are vital, so far as the difference between hypothesis and theory is concerned:. Both hypothesis and theory are testable and falsifiable. When a hypothesis is proved true, by passing all critical tests and analysis, it becomes a theory. So, the hypothesis is very different from theory, as the former is something unproven but the latter is a proven and tested statement.

Key Differences Between Hypothesis and Theory The points given below are vital, so far as the difference between hypothesis and theory is concerned: Hypothesis refers to a supposition, based on few pieces of evidence, as an inception of further research or investigation. A theory is a well-affirmed explanation of natural phenomena, which is frequently validated through experimentation and observation.

While the hypothesis is based on a little amount of data, the theory is based on a wide set of data. The hypothesis is an unproven statement; that can be tested. On the other hand, the theory is a scientifically tested and proven explanation of fact or event. Hypothesis relies on suggestions, prediction, possibility or projects whereas a theory is supported by evidence and is verified. The hypothesis may or may not be proved true, so the result is uncertain. On the contrary, the theory is one, that is assumed to be true and so its result is certain.

Hypothesis and theory are two levels of the scientific method, i. Leave a Reply Cancel reply Your email address will not be published. An educated guess, based on certain data, as an inception for further research or investigation is called hypothesis.

A theory is a rational type of abstract thinking about a phenomenon , or the results of such thinking. The process of contemplative and rational thinking often is associated with such processes like observational study , research. Theories may either be scientific or other than scientific or scientific to less extent. Depending on the context, the results might, for example, include generalized explanations of how nature works. The word has its roots in ancient Greek , but in modern use it has taken on several related meanings. In modern science , the term "theory" refers to scientific theories , a well-confirmed type of explanation of nature , made in a way consistent with scientific method , and fulfilling the criteria required by modern science. Such theories are described in such a way that scientific tests should be able to provide empirical support for it, or empirical contradiction " falsify " of it.

Hypothesis

In casual, non-scientific conversation the words hypothesis and theory are often used to mean the same thing: an idea, or notion, or hunch about something. In reality, they are quite different.

Difference Between Hypothesis and Theory

A hypothesis plural 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. Even though the words "hypothesis" and " theory " are often used synonymously, a scientific hypothesis is not the same as a scientific theory.

The primary tool, in the research process, is a hypothesis, that intends to suggest new experiments and observations. There are many experiments which are undertaken with the sole objective of testing hypothesis.

A research hypothesis is a specific, clear, and testable proposition or predictive statement about the possible outcome of a scientific research study based on a particular property of a population, such as presumed differences between groups on a particular variable or relationships between variables. Specifying the research hypotheses is one of the most important steps in planning a scientific quantitative research study. A quantitative researcher usually states an a priori expectation about the results of the study in one or more research hypotheses before conducting the study, because the design of the research study and the planned research design often is determined by the stated hypotheses. Thus, one of the advantages of stating a research hypothesis is that it requires the researcher to fully think Show page numbers Download PDF.

Although many have taken science classes throughout the course of their studies, people often have incorrect or misleading ideas about some of the most important and basic principles in science. Most students have heard of hypotheses, theories, and laws, but what do these terms really mean? Prior to reading this section, consider what you have learned about these terms before. What do these terms mean to you?

When thinking about ideas in a scientific context the ideas in question get described according to the level of corroboration and scrutiny they have recieved. The first step in the scientific process is to propose a solution or answer to the problem or question. In science, this suggested solution or answer is called the hypothesis, and this is one of the most important steps a scientist performs. A scientific hypothesis is an informed, testable, and predictive solution to a scientific problem that explains a natural phenomenon, process, or event. Scientific method requires that one can test a hypothesis.
