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. We make an "educated guess. We set out to prove or disprove the hypothesis.

How to Write a Hypothesis The solution of a scientific problem never begins directly with experiment. This procedure is preceded by a very important stage associated with the hypothesis. The scientific hypothesis is a statement containing an assumption about the solution of the problem faced by the researcher.

Theoretical background In formulating the hypothesis, you build an assumption about how you intend to achieve the stated goal of the study.

There are different types of scientific hypotheses. Some of them are: Hypotheses are descriptive and explanatory. In the descriptive hypothesis, the relationship between cause and effect is described, while the conditions, factors dictating the mandatory nature of the investigation are not disclosed.

This hypothesis does not have the property of predictability. In the explanatory hypothesis, conditions and factors are disclosed, under which observance will necessarily occur. This hypothesis is of a prognostic nature.

Properties of the scientific hypothesis. The hypothesis must correspond to meaningful facts. The hypothesis must be empirically verifiable. The hypothesis must be consistent with existing reliable knowledge. The hypothesis should be fundamentally refuted.

Preparation to writing hypothesis There are several steps you need to make before to proceed to writing a hypothesis: Before engaging in the formulation of the hypothesis, carefully study the literature on the problem.

Writing a hypothesis assumes that you already know the material, and therefore — can make assumptions about what processes will be observed in this or that case.

Pay attention to those works on your problem, which are of research character: You can either take a prepared hypothesis or adapt it to your work. Note that there can be two hypotheses in the study, one of which is proved, and the second is refuted thus, two variants of the dynamics of the situation are taken into account.

In this case, we can formulate the hypothesis as follows: It can not refute that the level of anxiety of students does not depend on their current academic performance. The level of anxiety in students with excellent and good performance is higher than in students with low and satisfactory performance.

The formulation of the hypothesis necessarily implies the need to apply methods of mathematical analysis, otherwise research can not claim the scientific nature of the results.

At the end of the study, the results of qualitative and quantitative analysis are summarized, conclusions are drawn about the statistical significance of the hypothesis.Nevertheless, a hypothesis can also represent an assertion that reports a discovered natural model, which is known as a generalizing hypothesis.

A hypothesis may lead to a prediction. A prediction is an assertion which suggests that a particular factor will exert an influence on or determine a transformation in a different factor, as part of the outcome of a coordinated trial.

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. Examples of the Null Hypothesis To write a null hypothesis, first start by asking a question.

Rephrase that question in a form that assumes no . The hypothesis must be refined to give a little direction. “Rainbow trout suffer more lice when water levels are low.” Now there is some directionality, but the hypothesis is not really testable, so the final stage is to design an experiment around which research can be designed, i.e.

a testable hypothesis. Nevertheless, a hypothesis can also represent an assertion that reports a discovered natural model, which is known as a generalizing hypothesis.
