What is the importance of hypothesis in research?

A hypothesis forms the base of research that defines the relationship between two or more research variables. The main topic of discussion is defined based on the hypothesis statement that is clear and concise.

Basic characteristics of a hypothesis:

  • It is self-explanatory and consistent.
  • It does not contradict itself.
  • It is testable and clearly stated.
  • It defines the relationship between research variables.
  • It contains facts and evidence to support the author’s claims.

A research hypothesis talks about the possible outcome or result of the experiment. The key concepts and the connection between the statement of problem and literature review are defined using the hypothesis.

It is written in a declarative form, which makes it brief and to the point. Formulate a hypothesis in a testable form so that your readers can understand the core concept of the research.

Steps involved in writing a research paper:

Formulation of question: A research question is clear and concise, and it focuses on the area of concern. It states the problem that the author is trying to solve through the research.

Background research: Analyze research papers published in your field of study. Provide context by sharing your ideas and observations on the related research theories and scientific concepts.

Create a hypothesis: State the expected outcome and define the research variables and establish a link between them.

Reporting data: Use tables and graphs to represent the data by referring to the images and charts correctly. Determine whether you want to use the decimal system or alphanumeric system.

Research findings: Write a result overview and report the research findings. Try to be as specific as possible while summarizing the results.

Before writing the introduction section, ensure that your hypothesis is based on the main topic of research. Double-check the independent and dependent variables and ensure that it can be tested.

What are the different types of research hypothesis?

Research Hypothesis: The research hypothesis also known as the non-parametric hypothesis; it states the nature of the relationship between the research variables. The variables identify possible solutions to the main problem statement.  As the data is not represented in quantitative form, the research hypothesis is not tested by statistical methods.

Null hypothesis: This hypothesis simply establishes that no statistical importance in a set of data exists. It proves that no variation exists between two or more variables.

Alternative hypothesis: This hypothesis is the opposite of the null hypothesis. If the null hypothesis is rejected, then you can use the alternative hypothesis to complete the experiment.

Various functions of the research hypothesis:

  • To test theories and concepts
  • To confirm or disconfirm theories
  • To identify the right methodology or tools
  • To provide a general framework
  • To discover new prospects of the research topic

Hypothesis testing:

State the hypothesis: Identify the hypothesis that needs to be tested? Which type of hypothesis are you working on? Is it an alternative hypothesis or null hypothesis?

Plan: How do you plan to utilize the sample data? What methods are you going to use for testing the hypothesis?

Analyze: Perform sample analysis to test your hypothesis. Compare two different sets of data you have received before and after the sample selection.

Acceptance/Rejection: Evaluate the results by subjecting the hypothesis to tests. You can determine whether or not the hypothesis is valid based on the test results.
