Definitions:

Critical Value

A threshold value used in hypothesis testing that defines the boundary between the region where the null hypothesis is rejected and the region where it is not rejected.

Test Statistic

A value calculated from sample data during hypothesis testing used to decide whether to reject the null hypothesis.

P-value

The probability of obtaining test results at least as extreme as those observed during the test, assuming that the null hypothesis is correct.

Critical Value

A point on the scale of the test statistic beyond which we reject the null hypothesis, it's determined by the chosen significance level.
