Definitions:

P-Value

The p-value is a measure in statistics that helps determine the significance of results from a hypothesis test, indicating the probability of observing the results given that the null hypothesis is true.

Level Of Significance

A threshold or criterion for judging whether a statistical result is significant, commonly set at values like 0.05 or 0.01, indicating the risk of a Type I error.

Null Hypothesis

A default hypothesis that there is no significant difference or effect, tested against to determine the likelihood of the alternative hypothesis.

One-Tail Test

A statistical test in which the region of rejection is on only one side of the sampling distribution, used to determine if a parameter is greater than or less than a certain value.
