Research Hypothesis Vs Null Hypothesis

Research Hypothesis Vs Null Hypothesis

The difference between Research Hypothesis Vs Null Hypothesis is as follows:

Research Hypothesis

A Research Hypothesis is a tentative statement that proposes a relationship between two or more variables. It is based on a theoretical or conceptual framework and is typically tested through empirical research.

Null Hypothesis

A Null Hypothesis is a statement that proposes that there is no relationship between two or more variables. It is the opposite of the research hypothesis and is used as a comparison in statistical analysis.

Comparison Table:

AspectResearch HypothesisNull Hypothesis
DefinitionTentative statement that proposes a relationship between two or more variablesStatement that proposes no relationship between two or more variables
PurposeTo guide research and provide a framework for testing the relationship between variablesTo provide a comparison for the research hypothesis in statistical analysis
FormatExpressed in a declarative sentence that describes the expected direction and strength of the relationship between variablesExpressed in a declarative sentence that proposes no effect or relationship between variables
TestingTested through empirical researchTested against the research hypothesis in statistical analysis
ConclusionSupported if statistical analysis provides evidence to reject the null hypothesisRejected if statistical analysis provides evidence to support the research hypothesis
Example“There is a positive relationship between physical exercise and mental health.”“There is no relationship between physical exercise and mental health.”

In summary, a research hypothesis proposes a relationship between variables, while a null hypothesis proposes no relationship between variables. The research hypothesis guides empirical research, while the null hypothesis is used as a comparison in statistical analysis. The research hypothesis is supported if statistical analysis provides evidence to reject the null hypothesis, while the null hypothesis is rejected if statistical analysis provides evidence to support the research hypothesis.
