The null hypothesis is the statistical hypothesis that predicts no relationship exists between variables or that there is no significant difference between groups. It is not always false, as it is important to consider and test both the null and alternative hypotheses. It is also not usually the same as the research hypothesis, as the research hypothesis is the hypothesis being investigated by the researcher. The null hypothesis is not predicting a treatment effect, but rather predicting no effect.
