How to write a research hypothesis statement

A Strong Hypothesis

Instead, you make an "educated guess" based on what you already know and what you have already learned from your research. I think that leaves change colors in the fall because they are not being exposed to as much sunlight. It builds upon previously accumulated knowledge e.

If these statements had not been written carefully, they may not have been a hypotheses at all. For example, it is a common observation that objects that are thrown into the air fall toward the earth.

These examples contain the words, if and then. The question comes first. Your hypothesis is not the scientific question in your project. A better way to write a hypotheses is to use a formalized hypotheses Example: The above hypothesis is too simplistic for most middle- to upper-grade science projects, however.

If a hypothesis is continually supported, it may evolve into a theory Leedy and Ormrod, Make sure your hypothesis is "testable. It provides a tentative explanation for a phenomenon under investigation. Reading your hypothesis should tell a teacher or judge exactly what you thought was going to happen when you started your project.

A theory is describes as "an organized body of concepts and principles intended to explain a particular phenomenon" Leedy and Ormrod, If your science fair is over, leave a comment here to let us know what your hypothesis was for your project.

Test Your Hypothesis by Doing an Experiment Analyze Your Data and Draw a Conclusion Communicate Your Results Following the scientific methodwe come up with a question that we want to answer, we do some initial research, and then before we set out to answer the question by performing an experiment and observing what happens, we first clearly identify what we "think" will happen.

An example of a well known law is the law of gravity Leedy and Ormrod, Bacterial growth may be affected by temperature.

What you "think" will happen, of course, should be based on your preliminary research and your understanding of the science and scientific principles involved in your proposed experiment or study.

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, However, hypotheses are not unique to research.

How to Write a Hypothesis

Why do leaves change colors in the fall? A theory that is continually validated over time by a growing body of data becomes a law. Chocolate may cause pimples All of these are examples of hypotheses because they use the tentative word "may.

Hypothesis Generation Often times, an investigator will formulate a hypothesis based on the problem or subproblems of the research. If skin cancer is related to ultraviolet light, then people with a high exposure to uv light will have a higher frequency of skin cancer.

If leaf color change is related to temperature, then exposing plants to low temperatures will result in changes in leaf color. We set out to prove or disprove the hypothesis. As Dave explains, "A hypothesis is a possible explanation for something that is observed in nature.Step 5: Hypothesis Statement Hypothesis Statement (will be worked on in class prior to due date) Your hypothesis statement will be turned in during science class, reviewed by the teacher and returned.

Below is a short explanation of a hypothesis statement and some examples of hypothesis statements. A better way to write a hypotheses is to. Start by understanding just what a hypothesis is! Generally used in quantitative research studies, it's an educated guess or prediction about the relationship between two variables.

Step 5: Hypothesis Statement

It must be a testable statement something that. The hypothesis is a clear statement of what is intended to be investigated. It should be specified before research is conducted and openly stated in reporting the results. A research hypothesis is a statement of expectation or prediction that will be tested by research.

Before formulating your research 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.

A Strong Hypothesis We write a hypothesis. We set out to prove or disprove the hypothesis. What you "think" will happen, of course, should be based on your preliminary research and your understanding of the science and scientific principles involved in your proposed experiment or study.

Make sure your hypothesis is a specific statement.
