Definitions:

Null Hypothesis

A hypothesis that assumes no statistical significance exists in a set of given observations, typically asserting that no variation or effect is present.

Type I Error

The error that occurs when a true null hypothesis is incorrectly rejected.

Test Statistic

A value calculated from sample data used to make a decision whether to reject the null hypothesis in hypothesis testing.

Test Statistic

A value calculated from sample data during hypothesis testing, used to determine the probability of observing the sample data under the null hypothesis.
