How to Formulate an Effective Research Hypothesis
- State the problem that you are trying to solve. Make sure that the hypothesis clearly defines the topic and the focus of the experiment.
- Try to write the hypothesis as an if-then statement.
- Define the variables.

A hypothesis is an assumption about how two or more variables are related; it makes a conjectural statement about the relationship between those variables. In sociology, the hypothesis will often predict how one form of human behavior influences another. In research, independent variables are the cause of the change.
Within social science, a hypothesis can take two forms. It can predict that there is no relationship between two variables, in which case it is a null hypothesis. Researchers seek to determine whether or not their hypothesis, or hypotheses if they have more than one, will prove true.
A qualitative hypothesis testing strategy follows the basic procedure of hypothesis testing. The social scientist generates a hypothesis in response to a research question. The social scientist then compares his or her expectation against the observed world.
What is hypothesis example?
Examples of Hypothesis:
- If I replace the battery in my car, then my car will get better gas mileage.
- If I eat more vegetables, then I will lose weight faster.
- If I add fertilizer to my garden, then my plants will grow faster.
- If I brush my teeth every day, then I will not develop cavities.
What is a good hypothesis example?
Here’s an example of a hypothesis: If you increase the duration of light, (then) corn plants will grow more each day. The hypothesis establishes two variables, length of light exposure, and the rate of plant growth. An experiment could be designed to test whether the rate of growth depends on the duration of light.
How do you write a hypothesis?
Tips for Writing a Hypothesis
- Don’t just choose a topic randomly. Find something that interests you.
- Keep it clear and to the point.
- Use your research to guide you.
- Always clearly define your variables.
- Write it as an if-then statement. If this, then that is the expected outcome.
How do you write an alternative hypothesis?
Always write the alternative hypothesis, typically denoted with Ha or H1, using less than, greater than, or not equals symbols, i.e., (≠, >, or <). If we reject the null hypothesis, then we can assume there is enough evidence to support the alternative hypothesis. Never state that a claim is proven true or false.
How is a hypothesis verified?
A hypothesis requires more work by the researcher in order to either confirm or disprove it. The formulated hypothesis is then evaluated where either the hypothesis is proven to be “true” or “false” through a verifiability- or falsifiability-oriented experiment.
What is hypothesis in research writing?
A hypothesis is a tentative statement about the relationship between two or more variables. It is a specific, testable prediction about what you expect to happen in a study.
What are the sources of hypothesis in research?
Main Sources of Hypothesis in Research
- Personal Experience.
- Imagination & Thinking.
- Observation.
- Scientific Theory.
- Previous Study.
- Culture.
What is hypothesis and how do you formulate it?
A hypothesis is used to explain a phenomenon or predict a relationship in communication research. Formulating a hypothesis requires a specific, testable, and predictable statement driven by theoretical guidance and/or prior evidence. A hypothesis can be formulated in various research designs.
How do you write a testable hypothesis?
How to Propose a Testable Hypothesis
- Try to write the hypothesis as an if-then statement.
- Identify the independent and dependent variable in the hypothesis.
- Write the hypothesis in such a way that you can prove or disprove it.
- Make sure you are proposing a hypothesis you can test with reproducible results.
Our alpha level is our level of confidence for avoiding a Type One error. In other words, with an alpha of. 05 (which is the most common in the social sciences), we’re 95 percent sure we won’t accidentally reject a true null hypothesis.
What is the probability of not rejecting the alternative hypothesis?
Power is the probability of rejecting the null hypothesis when, in fact, it is false. Power is the probability of making a correct decision (to reject the null hypothesis) when the null hypothesis is false. Power is the probability that a test of significance will pick up on an effect that is present.
