![]() It is usually pronounced as “h-nought” or “H-null”. To be more specific, hypothesis testing gives precise criteria for rejecting or accepting a null hypothesis within a level known as the confidence level.Ī Null Hypothesis is denoted by the symbol H 0 in statistics. ![]() ![]() Testing (which involves accepting, approving, rejecting, or disproving) the null hypothesis and thus concluding that there are or we can say that there are no grounds for believing that there is any relationship between two phenomena is basically a central task in the modern practice of science in the field of statistics. We can define a null hypothesis as a general statement or a default position that says there is no relationship between two measured phenomena or there is no association among groups. Hypothesis clearly explains and predicts the expected outcome and it indicates the types of experimental design and directs the study of any research process. Hypothesis helps the researcher to translate any given problem to a clear explanation for the outcome of the study. In Statistics, a hypothesis can be defined as a formal statement, which gives an explanation about the relationship between any two or more variables of the specified population. Before understanding the Null Hypothesis in detail, let us first understand the definition of the Hypothesis.
