In research, a null hypothesis means that no results will be found. An alternative hypothesis means that results will be found.
In research, a null hypothesis means that no results will be found. An alternative hypothesis means that results will be found.
The hypothesis in research is an idea or concept that may be true. Through proper experimentation, a hypothesis can become a fact. So, in research, you test a hypothesis to see if it is true. You will see that the null hypothesis, from the related link, is what you are testing against. Perhaps you have a new medicine, and you want to know if it improves the health of a patient. Your null hypothesis is that this treatment does not cause any improvement.

A hypothesis is composed of two parts: the null hypothesis, which states that there is no effect or no difference between groups, and the alternative hypothesis, which states that there is an effect or a difference. These two components together form the basis for statistical testing and inference in research.
Some researchers say that a hypothesis test can have one of two outcomes: you accept the null hypothesis or you reject the null hypothesis. Many statisticians, however, take issue with the notion of "accepting the null hypothesis." Instead, they say: you reject the null hypothesis or you fail to reject the null hypothesis. Why the distinction between "acceptance" and "failure to reject?" Acceptance implies that the null hypothesis is true. Failure to reject implies that the data are not sufficiently persuasive for us to prefer the alternative hypothesis over the null hypothesis.
A hypothesis is a proposed explanation or prediction that is based on limited evidence and subject to further investigation. It serves as the starting point for scientific research and helps guide the design of experiments or studies. There are two main types of hypotheses: null and alternative. A null hypothesis states that there is no relationship or difference between variables, while an alternative hypothesis asserts that there is a relationship or difference between variables.
The null hypothesis is the statement that there is no relationship between two observations.
