Developing a hypothesis (with example)
- Ask a question. Writing a hypothesis begins with a research question that you want to answer.
- Do some preliminary research.
- Formulate your hypothesis.
- Refine your hypothesis.
- Phrase your hypothesis in three ways.
- Write a null hypothesis.
What is a good psychology hypothesis?
Characteristics of a Good Hypothesis
First, a good hypothesis must be testable and falsifiable . We must be able to test the hypothesis using the methods of science and if you’ll recall Popper’s falsifiability criterion, it must be possible to gather evidence that will disconfirm the hypothesis if it is indeed false.
What are 3 examples of a hypothesis?
Here are some examples of hypothesis statements: If garlic repels fleas, then a dog that is given garlic every day will not get fleas. If sugar causes cavities, then people who eat a lot of candy may be more prone to cavities. If ultraviolet light can damage the eyes, then maybe this light can cause blindness.
What is a good example of a hypothesis?
A simple hypothesis suggests only the relationship between two variables: one independent and one dependent. Examples: If you stay up late, then you feel tired the next day. Turning off your phone makes it charge faster.

What 3 words should your hypothesis include?
Step 3: State your hypothesis
- Now it’s time to state your hypothesis.
- The hypothesis is often written using the words “IF” and “THEN.” For example, “If I do not study, then I will fail the test.” The “if’ and “then” statements reflect your independent and dependent variables.
What is hypothesis and its example?
A simple hypothesis is a statement made to reflect the relation between exactly two variables. One independent and one dependent. Consider the example, “Smoking is a prominent cause of lung cancer.” The dependent variable, lung cancer, is dependent on the independent variable, smoking.
What is an example of a simple hypothesis?
Simple Hypothesis
It shows a relationship between one dependent variable and a single independent variable. For example – If you eat more vegetables, you will lose weight faster. Here, eating more vegetables is an independent variable, while losing weight is the dependent variable.
What is a simple hypothesis?
Simple Hypothesis. A simple hypothesis predicts the relationship between a single dependent variable and a single independent variable. Complex Hypothesis. A complex hypothesis predicts the relationship between two or more independent and dependent variables.
What is a good research hypothesis?
Good hypotheses are testable hypotheses. This means that one can actually carry out the intent of the question reflected by the hypoth- esis. For example, number of hours of parental reading and outcome scores as measured by a test of comprehension are all objective and can be incorporated reliably.
How do you write a perfect hypothesis?
How to Write Hypothesis in Research
- Predicts the relationship and outcome.
- Simple and concise – avoid wordiness.
- Clear with no ambiguity or assumptions about the readers’ knowledge.
- Observable and testable results.
- Relevant and specific to the research question or problem.
How do you start a hypothesis?
Steps for How to Write a Hypothesis
- Ask a question.
- Gather preliminary research.
- Formulate an answer.
- Write a hypothesis.
- Refine your hypothesis.
- Create a null hypothesis.
How do you choose a hypothesis?
There are 5 main steps in hypothesis testing:
- State your research hypothesis as a null hypothesis and alternate hypothesis (Ho) and (Ha or H1).
- Collect data in a way designed to test the hypothesis.
- Perform an appropriate statistical test.
- Decide whether to reject or fail to reject your null hypothesis.
What should you not do in a hypothesis?
Avoid These 14 Common Pitfalls
- Not knowing what you want to learn.
- Using quantitative methods to answer qualitative questions (and vice versa).
- Starting with untestable hypotheses.
- Not having a reason for why your change will have the desired impact.
- Testing too many variations.
What happens if your hypothesis has failed?
When a hypothesis fails, the first thing you should do is examine the data closely. Then use your research and data to determine a possible reason why the hypothesis was incorrect. Once you come up with a reason your hypothesis may have failed, you can start thinking of ways to check your assumption.
How long is a hypothesis supposed to be?
A good guideline for a clear and direct hypothesis statement is to aim to keep the hypothesis to 20 words or less. An effective hypothesis is one that can be tested. In other words, students need to ensure that the hypothesis includes information on what they plan to do and how they plan to make it happen.
What is it called when a hypothesis is wrong?
The proof lies in being able to disprove
A hypothesis or model is called falsifiable if it is possible to conceive of an experimental observation that disproves the idea in question. That is, one of the possible outcomes of the designed experiment must be an answer, that if obtained, would disprove the hypothesis.
Can a hypothesis be proven true?
In science, a hypothesis is an educated guess that can be tested with observations and falsified if it really is false. You cannot prove conclusively that most hypotheses are true because it’s generally impossible to examine all possible cases for exceptions that would disprove them.
Can a hypothesis be changed?
A hypothesis is very tentative; it can be easily changed.
Can hypothesis be accepted or rejected?
We assume that the null hypothesis is correct until we have enough evidence to suggest otherwise. After you perform a hypothesis test, there are only two possible outcomes. When your p-value is less than or equal to your significance level, you reject the null hypothesis. The data favors the alternative hypothesis.
Can a hypothesis be verified?
A hypothesis requires more work by the researcher in order to either confirm or disprove it. In due course, a confirmed hypothesis may become part of a theory or occasionally may grow to become a theory itself. Normally, scientific hypotheses have the form of a mathematical model.
