Null Hypothesis

A statement suggesting that there is no significant difference or relationship between specified populations, any observed difference being due to sampling or experimental error.

Null Hypothesis

A statement in statistical hypothesis testing that assumes no effect or no difference between phenomena or populations.

Level of Risk
