Rejection Region

The rejection region is used in hypothesis testing. When a sample measurement, called a test statistic, falls into this area, the null hypothesis will be rejected. Please also see hypothesis testing.

The rejection region is also called the "tail" of the graph since the area is small and extends away from the main body of the graph.
