How to write a medical research hypothesis

Writing Research Questions and Hypotheses Research Questions and Hypotheses The purpose of this module is to discuss research questions and research hypotheses and to provide definitions, comparisons and examples of both. Define research question and research hypothesis. Explain the difference between a research question and a research hypothesis and describe the appropriate use of each. Describe the purpose of each and understand the importance of a well-developed question or hypothesis.

Generating A Research Hypothesis The purpose of this page is to introduce the concept of the research hypothesis and describe how it is generated. Hypothesis Definition "A hypothesis is a logical supposition, a reasonable guess, an educated conjecture.

It provides a tentative explanation for a phenomenon under investigation. An example of a formalized research hypothesis is "If skin cancer is related to ultraviolet lightthen people with a high exposure to uv light will have a higher frequency of skin cancer" http: However, hypotheses are not unique to research.

Hypotheses are constantly generated in the human mind as we work to understand day-to-day phenomena. By formulating a series of reasonable guesses of cause and effect we are able to understand and explore the events in our surrounding environment Leedy and Ormrod, An investigator may refer to the hypothesis to direct his or her thought process toward the solution of the research problem or subproblems.

The hypothesis helps an investigator to collect the right kinds of data needed for the investigation. Hypotheses are also important because they help an investigator to locate information needed to resolve the research problem or subproblems Leedy and Ormrod, Support or Reject A hypothesis is never proved or disproved!

Jul 28,  · How to Write a Hypothesis. A hypothesis is a description of a pattern in nature or an explanation about some real-world phenomenon that can be tested through observation and experimentation. Write a research hypothesis. Often, hypotheses are stated in the form of if-then sentences. For example, "if children are given caffeine, 79%(55). 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. Planning My Research Question or Hypothesis – This resources contains a link to a PowerPoint presentation and a series of tutorials that contain examples and tips for writing research .

In fact, an investigator who sets out to prove a hypothesis would lose the impartiality of the research investigation Leedy and Ormrod, In research, an investigator is able to either support or reject a hypothesis.

If a hypothesis is rejected, it will lead an investigator to new hypothesis to explain the phenomenon in question. If a hypothesis is continually supported, it may evolve into a theory Leedy and Ormrod, As a hypothesis is continually supported over time by a growing body of data, it becomes a theory.

A theory is describes as "an organized body of concepts and principles intended to explain a particular phenomenon" Leedy and Ormrod, A theory is similar to a hypothesis in that it offers a tentative explanation for a phenomenon that new data will either support or not support.

Both are supported or rejected based on testing by various investigators under different conditions.

Hypothesis Definition

An example of a well known theory is Einstein's theory of relativity Leedy and Ormrod, A theory that is continually validated over time by a growing body of data becomes a law. An example of a well known law is the law of gravity Leedy and Ormrod, Hypothesis Generation Often times, an investigator will formulate a hypothesis based on the problem or subproblems of the research.

The hypothesis is driven by the research question Leedy and Ormrod, The University of Wisconsin - Eau Claire McIntyre Library website contains guidelines for developing a hypothesis according to your research approach or method.Jul 28,  · How to Write a Hypothesis.

A hypothesis is a description of a pattern in nature or an explanation about some real-world phenomenon that can be tested through observation and experimentation.

Write a research hypothesis. Often, hypotheses are stated in the form of if-then sentences. For example, "if children are given caffeine, 79%(55). This is a testable hypothesis - he has established variables, and by measuring the amount of oxygen in the water, eliminating other controlled variables, such as temperature, he can see if there is a correlation against the number of lice on the fish.

Medical Hypotheses

This is an example of how a gradual focusing of research helps to define how to write a hypothesis. The hypothesis is driven by the research question (Leedy and Ormrod, ). The University of Wisconsin - Eau Claire McIntyre Library website contains guidelines for developing a hypothesis according to your research approach or method.

In the above example, a researcher might speculate that the decline in the fish stocks is due to prolonged over fishing.
