Definitions:

P-values

Measures that help determine the significance of results obtained in statistical hypothesis testing, indicating the probability of observing results if the null hypothesis were true.

Levels Of Significance

A threshold in hypothesis testing that determines the probability at which the null hypothesis is rejected, often denoted by alpha.

P-value

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

Test Statistic

A calculated value from sample data that is used in a hypothesis test to determine whether to reject the null hypothesis, based on the likelihood of observing the sample data under the null hypothesis.
