How to Write a Hypothesis With Simple Steps

how to write a hypothesis

Hypotheses are a way to test relationships between two or more things by scientific research. It is an assumption of what will happen when you do something. It's like an educated guess, but scientific research can test it based on available facts and evidence.

The hypothesis is the fundamental building block for the future research study. Therefore, it should be clear, direct, and achievable.

It's true that writing a hypothesis can be daunting, but if you understand the types of hypotheses and how they're structured, then it won't seem too hard.

Therefore, continue reading this blog and get to know how to write a great hypothesis with the help of professionally written examples.

What is Hypothesis?

Hypotheses are an important part of the research process. A hypothesis is something you think might be true, but you don't know for sure. Sometimes you have to write several hypotheses for some research projects that address different aspects of your research question.

Hypotheses are not guesses. They should be based on theories and knowledge that is already known, which means they can also get tested with scientific research methods to see if their predictions come true or false.

Hypotheses always use language that discusses variables. Variables can be things like objects, events, or concepts that you can see.

A hypothesis is a plan that tells you what you are going to do in your research. You need to have a good hypothesis so you can do good research. The reader of your paper wants to know if your hypothesis was true or not. So, you need to write it clearly in your paper's introduction and/or abstract.

When constructing your hypothesis, it is important to be careful and precise. A minor flaw in your hypothesis could have a negative impact on the results of your experiment.

What are the Types of Hypothesis?

There are seven main types of hypotheses. Your hypothesis might fit into one or more of these categories. Remember, these categories are not exclusive, so your hypothesis might fit into more than one category.

Have a look at them to get a better idea.

  • Simple Hypothesis

    This hypothesis is also known as the basic hypothesis. A simple hypothesis is when the researcher shows the relationship between two independent and dependent variables.

    • Taking tobacco leads to lung cancer.
  • Complex Hypothesis

    A complex hypothesis is used to figure out how different things are related to each other. This type of hypothesis is also called a multivariate hypothesis because it includes lots of different variables.

    • The elderly who live in rural areas have a happiness level that is 3-5 points higher than younger adults.
    • When you eat too many of the wrong kinds of foods, it can increase your chances of developing heart disease.
  • Null Hypothesis

    The null hypothesis is always used when you have insufficient data to state the claim. It's denoted by “HO” and indicates no relationship between the dependent variable(s) and independent variables.

    • The color of light does not affect plant growth.
    • Cats typically live longer than dogs.
  • Alternative Hypothesis

    The alternative hypothesis is a statement that suggests an association between two variables. It is also known as a research hypothesis or a maintained hypothesis.

    The four types of alternative hypotheses are

    • Point Alternative
    • One-tailed directional hypothesis
    • Two-tailed directional hypothesis
    • Non-Directional Alternative Hypothesis
    • Daily consumption of green tea has a positive impact on my health.
  • Statistical Hypothesis

    In a statistical hypothesis, the researcher tests their statement based on observed data. In this type of hypothesis, you use statistics from an area to verify whether it can be logical or illogical for validity and reliability.

    • About 55% of the population is 70 years old or over globally.
    • A very small amount of people in the world have red hair.
    • One out of every five adults in the United States is illiterate.
  • Empirical Hypothesis

    An empirical hypothesis is a working hypothesis that is based on concrete data. Empirical hypotheses are different from logical hypotheses because they rely on data rather than theory.

    • Raising the basic salary of the waiter staff will not affect the number of tips customers give.
    • The cereal boxes that are sold in America have pictures on them.
    • Handwashing can help reduce the number of times you get sick.
  • Logical Hypothesis

    Logical Hypotheses are a popular way to establish relationships between variables without having any actual evidence. They're based on reasoning, but they lack the actual data.

    • People need air to breathe in order to live.
    • All living beings need to eat in order to survive.
    • Dinosaurs that had sharp, pointed teeth were probably carnivores.

You should be using different types of sentences when writing these different types of hypotheses. Moreover, always remember that a hypothesis is different from a thesis statement. A thesis statement summarizes your stance in an essay, while a hypothesis introduces your research question.

How to Write a Hypothesis?

The following are steps to take when writing a perfect hypothesis.

  1. 1. Ask a Question

    The scientific method begins with a question. Scientists use the six classic questions to ask questions about things: who, what, where, when, why, and how.

  2. 2. Conduct Preliminary Research

    Next, you will need to collect information about your topic. This depends on what you are trying to do. You might need to read several books, or you might be able to find the answer with a quick web search. Collect all of the information needed, but don't worry about proving or disproving anything just yet.

  3. 3. Define Your Variables

    When creating a hypothesis, it's important to consider which variables are independent and dependent.

  4. 4. Phrase Your Hypothesis

    The if-then format is a great way to phrase your hypothesis. When variables are involved, this format can be tricky. However, it does have the advantage of being able to express cause-and-effect relationships clearly and concisely.

  5. 5. Write Null Hypothesis

    The null hypothesis is a statistical test's default position, which implies there are no relationships between variables being studied. HO is just a shorter way of saying "null hypothesis."

Now, you can write a great hypothesis for your research paper with the help of this detailed guide. If you find yourself in need of some help, don’t hesitate; to reach out today! We are here at, ready and waiting to help you with your academic writing assignments.

How long is a hypothesis?

The most effective hypotheses are clear and concise. They should be no more than 20 words long and must be able to be tested. In order to create a testable hypothesis, you must include information on what you will do and how you will make it happen.

How to start a hypothesis sentence?

To begin writing a hypothesis, you first need to come up with a research question. The question should be focused and specific, and it should be possible to answer it within the confines of your project.

What are the key characteristics of a good hypothesis?

The key characteristics of a good hypothesis are:

  • Testable
  • Clear
  • Specify variables
