# 10+ Null Hypothesis Examples & Templates

Many scientific theories and discoveries that have contributed to the overall scientific knowledge and development have undergone an intense vetting process that requires statistical evidence. There are two types of hypothesis statements researchers need to make when making a research paper, which supposes the two or more possible outcomes the research will create.

## What Is a Null Hypothesis?

A null hypothesis is one of the two types of hypothesis statements the researcher writes as one of the two possible outcomes that can come from the research. The researcher will only write the null hypothesis when the research statement requires the researcher to provide statistical evidence through t-tests and other methods.

## How to Write Null Hypothesis

The null hypothesis follows a specific pattern that will deny any causation relationship between two or more variables, which makes it very easy to write and create a null hypothesis. If you want to know more about the null hypothesis you may read up on any of the links on the list above.

### Step 1: Create a Small Outline

The null hypothesis follows a very simple format that is very easy to follow. Start by creating or obtaining a short outline or a null hypothesis outline format that you will use in the creation of your null hypothesis.

### Step 2: Obtain the Variables Your Research Topic Uses

After you have created or found an outline you will use, you must obtain the set of variables you are investigating in your research. If you have a qualitative research question you will not need to create a null hypothesis.

### Step 3: Create the Null Hypothesis

When you have finished obtaining your variables, you can now create the null hypothesis of your research paper. Just be sure that the null hypothesis will deny any effect or relationship between the two variables.

### Step 4: If There are Three or More Variables, You Must Create Another Null Hypothesis

If there are three or more variables in the research question, you must create another null hypothesis for each pair of variables by repeating steps 1 to 3. You must do this until you finish all possible pairs of variables in the research topic.

## Null vs. alternative hypothesis; what is the difference between these two types of hypothesis statements?

The null hypothesis is a statement the researcher will make in their research statement, which would have a short phrase written under the specific context and theme that the factors have no relationship and effect with one another. At the same time, the alternative hypothesis is the juxtaposition of the null hypothesis which predicts the effect the factors have due to their relationship.

## How do you identify the null hypothesis?

The null hypothesis has a very clear simple sentence or compound sentence structure with various clear elements you can easily observe. The null hypothesis lists a premise that would deny and indicate that the two or more investigated variables have no effect. Not only that, but the null hypothesis should also deny any cause-and-effect relationships between the two or more variables listed in the theory.

## Do you need to have a null hypothesis when writing qualitative research?

No, because qualitative research uses inductive reasoning to create or generate codes to establish a cause-and-effect relationship. This means that qualitative research will never have a null and an alternative hypothesis as it will not use statistics as its main evidence.

The null hypothesis is one of the two types of hypothesis the researcher/s will create to accompany their research statement. People use these two types of hypotheses in statistics or research that requires said statistics, like Psychology. (See APA format) If one is planning to write a research paper with topics that require statistical analysis, one will need to know how to write a null hypothesis.
