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.
Two-Tail
Describes tests or intervals in statistics that consider extreme values in both tails of the distribution to test hypotheses or compute confidence intervals.
P-Value
The probability of observing data at least as extreme as the data actually observed, under the assumption that the null hypothesis is true.
