Definitions from the WebNull HypothesisDescription:The null hypothesis is a foundational concept in statistical analysis and testing. It is the statement that suggests there is no significant relationship or difference between the variables being studied. Sense 1: Statistical AnalysisIn statistical analysis, the null hypothesis is used to test and determine whether the observed data is statistically significant or if it occurred by chance. It assumes that there is no relationship or difference between variables. If the data contradicts the null hypothesis, an alternative hypothesis may be accepted. Sample Sentence:When conducting a research study, the null hypothesis would state that there is no difference in test scores between the two groups. Sense 2: Scientific ResearchIn scientific research, the null hypothesis is formulated to challenge or refute a research hypothesis. It attempts to disprove, rather than prove, a hypothesis by assuming no relationship or difference exists.
