The null hypothesis which assumes that there is no meaningful relationship between two variablesmay be the most valuable hypothesis for the scientific method because it is the easiest to test using a statistical analysis. The technical answer is : According to the principle of STATISTICS, the Null Hypothesis (H0) is stated as NEGATIVE. A good example of its practical use occurs when discussing the psychological aspects of eyewitness testimonies, and they generally affect four areas of this phenomenon: emotion and memory, system variables in the line-up, estimation of the duration of the event, and own-race bias.
