Type II Error

A statistical error that occurs when the null hypothesis is not rejected when it is false, also known as a "false negative" finding.

Level Of Significance

The threshold probability used in hypothesis testing to determine if the null hypothesis can be rejected, typically denoted by alpha (α).

Power Of The Test

The likelihood that a test will correctly reject a false null hypothesis, indicating the test's sensitivity.

Null Hypothesis

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