Detailed explanation-1: -A null hypothesis is a type of conjecture in statistics that proposes that there is no difference between certain characteristics of a population or data-generating process. The alternative hypothesis proposes that there is a difference.
Detailed explanation-2: -What is the Null Hypothesis? The null hypothesis states that there is no relationship between two population parameters, i.e., an independent variable and a dependent variable. If the hypothesis shows a relationship between the two parameters, the outcome could be due to an experimental or sampling error.
Detailed explanation-3: -The null hypothesis is that there is no relationship between the two variables. Correlation analysis provides information about: The direction of the relationship: positive or negative-given by the sign of the correlation coefficient.
Detailed explanation-4: -The null hypothesis is a typical statistical theory which suggests that no statistical relationship and significance exists in a set of given single observed variable, between two sets of observed data and measured phenomena.
Detailed explanation-5: -In scientific research, the null hypothesis (often denoted H0) is the claim that no relationship exists between two sets of data or variables being analyzed.
