A hypothesis statement or hypothesis states your predictions on what will be found in your research. If you ask how to write a hypothesis, there is no short answer. It is a preliminary response to your research query. You might have to write multiple hypotheses for certain research papers addressing various aspects. Moreover, you have to work with a variety of factors, parameters, and variables. In this blog, we will focus on how to make a hypothesis, and we will also check out examples of hypothesis.
Read on to get an insight.
Writing a Hypothesis and Various Types of Hypothesis
Before we proceed to how to write a good hypothesis, we will be taking a look at the various types of hypothesis.
The alternative hypothesis mentions that the two variables being analyzed are connected to each other (one variable has an effect on the other).
It states that the findings are not due to chance. In terms of supporting the hypothesis being investigated, they are significant.
Now, what is an example of alternative hypothesis? An alternate hypothesis is represented by Ha. For instance: Ha: More than 25% of voters in California voted in the primary election. P>30.
The null hypothesis states that the two variables being tested have no relationship with each other. In simple terms, one variable does not affect the other.
It further notes that outcomes are due to chance and are not relevant in terms of justifying the principle being investigated.
Now, what is an example of null hypothesis? Alternate hypothesis is represented by Ho. For example, Ho: The world is flat.
As far as nondirectional hypothesis is concerned, it predicts that the independent variable will have an effect on the dependent variable. However, the direction of the effect will be unknown.
Example of nondirectional hypothesis: There will be a difference in the numbers recalled by a child than by an elderly person.
Through the directional hypothesis, one gets to know the nature of the effect of the independent variable on the dependent variable.
Example of a directional hypothesis: Children who have proper nutrition over a span of five years will have a higher IQ than children not having one.
Now that you about the different types, we will proceed to the next section, where you learn about writing a hypothesis in depth.
How to Write a Good Hypothesis?
In this section, you will get to know about the nitty-gritty of how to make a good hypothesis. You should:
Ask Your Question
Writing a hypothesis starts with a question you want to answer in the research paper. Within the constraints of your project, the question should be oriented, descriptive, and researchable.
Do Some Research
This is one of the most crucial steps in how to form a hypothesis. It is important to base your initial answer to the question on what is already known about the subject. To form your conclusions, look for theories and existing studies.
You should create a conceptual structure (theoretical framework) at this point to define which variables you are going to research. You should also think about the relationships between them.
Write Down the Hypothesis (a Draft)
Since you have conducted some studies on the subject matter, you can come up with a rough hypothesis. This is the third step of how to form a hypothesis. But you should write it clearly and make it precise. You can work on it further.
Make Amendments to the Hypothesis
Now, if you are interested in the question of what makes a good hypothesis, you should pay attention to this point. You need to make sure that the hypothesis can be put to the test and is specific. There are different ways to express a hypothesis, but you should use self-explanatory terms. Furthermore, the hypothesis should contain:
- The pertinent variables
- The actual category that is being studied
- The projected consequence of the experiment or study
To verify the points, you should go through good hypothesis examples.
Arrange Your Hypothesis
Now you have to consider how to start a hypothesis. In order to identify the variables, you have to start with a simple prediction in if-then format. Usually, the first part of the sentence states the independent variable. The second part states the dependent variable.
For example: If first-year students attend classes regularly, their exam scores will improve, and their prospect will be bright.
Pen Down a Null Hypothesis
In the last step of what makes a good hypothesis, you have to write a null hypothesis. This is especially beneficial if you are working on statistical hypothesis testing. It is the default position where there is no connection between the variables.
If you are not able to follow the directions stated above, you should seek assessment help from professional experts.
Examples of Hypothesis You Should Check Out
Unless you go through research papers, you will not be able to understand the essence of the hypothesis. You will not understand how you have to validate the hypothesis throughout the paper. Mentioned below are certain examples of hypothesis.
Null Hypothesis Examples
We will analyze the examples in the question-hypothesis format.
Q1) Are young adults better at mathematics than the elderly?
Ho: Age is just a number and has no effect on mathematical ability.
Q2) Do you get pain relief by chewing willow bark?
Ho: There exists no difference in pain relief after chewing willow bark versus taking a placebo.
Q3) Do pet cats care about the color of their food?
Ho: Cats do not have food preferences based on color.
Directional Hypothesis Examples
- Depression scores decrease following a six-week intervention.
- Inverse relation exists between stress and health; health decreases as stress increases
- There exist a positive relationship between the number of books read by students and their scores on a reading test.
Nondirectional Hypothesis Examples
- College students will perform differently from elementary school students on a memory task.
Alternative Hypothesis Examples
- Researchers conduct a test on the quality of the water in a river. As per the alternative hypothesis, they find that the quality of water is poor in the second half when observed.
- Students in the College of Arts and Architecture are expected to be more left-handed than people in the general population.
- When the alternative hypothesis is HA: μ ≠ 0, the test possibly detects differences both greater than and less than the null value.
Hopefully, you will be able to understand the good hypothesis examples. If you struggle to come up with an interesting hypothesis, you should seek all assignment help from professional experts.
