How To Develop a Good Research Hypothesis?

Research papers are ever present in many academic and professional institutions. In 2020 alone, over seven million academic papers were published, highlighting their prevalence. Despite that vast number, they take time and effort to produce, with the hypothesis being one of the first parts researchers must devise.

A research hypothesis is a tentative statement that proposes a prediction or explanation of a specific phenomenon. In simpler terms, it guides the research from question to discovery. Without it, your research paper has no guide to follow, and you'll be unable to conduct targeted experiments and collect relevant data.

So, how does one develop a good research hypothesis? This article will explain the answer. Read on to learn the key steps in formulating the foundation of your paper.

Formulating Your Research Question

A research question is crucial to any qualitative or quantitative research. Often, your initial questions direct you to the hypothesis. For example, if you're into marketing and social media, your research question could be, 'What's the impact of social media influencers on brand marketing?' If your focus is medicine and advancing technology, your question could be, 'What are the effects of augmented reality on surgical training?'

Once you have your research question, you can begin moving toward your hypothesis. It involves reviewing existing literature, such as previous studies and scholarly databases. Some published studies may also have gaps in knowledge, prompting you to find the answers to address them. You can find more information here on how to write one.

Through your initial background research, you could find crucial variables and refine your question further. Take note of the methods, findings, and limitations, too. These will aid in formulating a compelling hypothesis.

Crafting Your Hypothesis

Now that you have a research question, you're ready to craft your hypothesis.

Research hypotheses often follow an 'if-then' or cause-and-effect structure incorporating the crucial variables. For instance, 'If (independent variable), then (dependent variable).'

Independent variables are the factors you'll change or manipulate in your experiments, while the dependent variables are the outcomes of those changes. With the topic of medicine and tech, your potential hypothesis could be, 'If surgeons practice surgical procedures using augmented reality, then real-life operations will have positive results.' In that example, the use of augmented reality in surgical training is the independent variable. Meanwhile, the positive results of real-life surgical procedures are the dependent variables.

Now, it’s high time to explore the characteristics of a good hypothesis, which include the following:

• Testable: Can you prove or disprove it through research methods? You should be able to collect data to support or refute your claim.
• Specific: It should be focused on a particular aspect of your research question. Broad or vague statements will be difficult to test.
• Clear and concise: Your research hypothesis must be easy to understand and unambiguous. Readers outside the field of study should be able to comprehend the methods and results, among others.
• Falsifiable: Good research hypotheses are open to the possibility of being wrong. Your research paper could lead the way for future researchers to discover new information or refine existing theories.

Keeping these characteristics in mind makes it easier to create a valid research hypothesis you can work on, regardless of what the results may be.

Tips for Writing a Strong Hypothesis

Even when you already have a clearer idea of what your hypothesis should be, you're not yet at the finish line. It's a living document you can and should refine based on your research findings. While you're doing initial research, you may encounter new or conflicting information. Revise your hypothesis as needed to ensure it aligns with the evidence you collect.

Also, consider the different types of hypotheses: directional vs. non-directional hypotheses. Directional hypotheses predict the specific direction of change between your variables. 'If A increases, then B improves,' is an example of this type. Non-direction hypotheses, on the other hand, only state a potential relationship without a specific direction. For example, 'A and B are related.'

Strong hypotheses become credible when they have consistent supporting evidence and lead to replicated studies. Replication involves multiple experiments using the same methods to refute or add credibility to the given claim. However, according to one research, studies that failed replication received more citations. So, it's possible to encounter references for your background research using flawed and unreliable studies.

Conclusion

Research papers are slightly different from regular essays since they require factual data that stems from a good research hypothesis. The hypothesis will be the backbone of your study, so it helps if you plan it around a particular question and follow the appropriate structure. Remember that it should also show the vital characteristics that make it valid for research and experiments.

So, the next time you're assigned to write a research paper, don't let intimidation bother you. Start at the first step—a simple question—and work your way from there. Critically review existing literature and revise when you need to. Soon enough, you'll have a research hypothesis and its consequent academic contribution to add to the growing pool of knowledge.
