| null hypothesis |
The statistical hypothesis that one variable (eg whether or not a study participant was allocated to receive an intervention) has no association with another variable or set of variables (eg whether or not a study participant died), or that two or more population distributions do not differ from one another. In simplest terms, the null hypothesis states that the results observed in a study are no different from what might have occurred as a result of the play of chance.

The null hypothesis is usually represented by the symbol H0, and is stated in order that it can be rejected as an explanation for the results of the experiment.

| null hypothesis |
in hypothesis testing, the hypothesis that anintervention has no effect, ie, that there is no true difference in outcomesbetween a treatment group and a control group. Typically, if statisticaltests indicate that the P value is at or above the specified alfa-level(eg, 0.01 or 0.05), then any observed treatment effect is not statisticallysignificant, and the null hypothesis cannot be rejected. ...
