Definitions:

Test Statistic

A value, derived from sample data, used in a hypothesis test to determine whether to reject the null hypothesis.

P-value

The probability of observing data at least as extreme as the observed data, given that the null hypothesis is true.

Null Hypothesis

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

Significance Level

The probability of rejecting the null hypothesis in a statistical test when it is actually true, typically denoted by alpha (α), used as a threshold to gauge the strength of the evidence against the null hypothesis.
