Alternative Hypothesis

In hypothesis testing, it is the hypothesis that suggests there is an actual effect or relationship present in the population.

P-value

The chance of encountering outcomes in a test that are as extreme or exceed the observed findings, given that the null hypothesis holds.

Test Statistic

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

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.
