# Null Hypothesis - SAGE Research Methods

1. A prediction is a specific hypothesis
2. Question a relationship between 2 or more variables
3. A suggested answer to a problem
4. It should be testable
5. Meta - analysis -- Hypothesis based on past research.
6 . Null hypothesis H0: No difference between groups
g. Alternate Hypothesis H1: There is a difference

## Null Hypothesis Significance Testing - SAGE Research Methods

### Research Methods | Validity (Statistics) | Null Hypothesis

the opposite of the research hypothesis. The null hypothesis states that any effects observed after treatment (or associated with a predictor variable) are due to chance alone. Statistically, the question that is being answered is "If these samples came from the same population with regard to the outcome, how likely is the obtained result?"

### Some Basic Null Hypothesis Tests | Research Methods …

A null hypothesis (H0) exists when a researcher believes there is no relationship between the two variables, or there is a lack of information to state a scientific hypothesis. This is something to attempt to disprove or discredit.

### you can postulate your null hypothesis as A ..

As such, by taking a hypothesis testing approach, Sarah and Mike want to generalize their results to a population rather than just the students in their sample. However, in order to use hypothesis testing, you need to re-state your research hypothesis as a null and alternative hypothesis. Before you can do this, it is best to consider the process/structure involved in hypothesis testing and what you are measuring. This structure is presented .

### Converting research questions to hypothesis is a simple task

Sorensen

Question 1
A research hypothesis is an assumption made by the researcher before undertaking the actual research and forms part of the expected outputs and research results.

When we pose a research question, we want to know whether the outcome is due to the treatment (independent variable) or due to chance (in which case our treatment is probably not effective). For example, the claim that tutoring improves math performance generally does not predict exactly how much improvement. Each level of improvement has a different probability associated with it, and it would take a long time and a great deal of effort to specify the probability of each of the possible outcomes that would support our research hypothesis.
