Definitions:

P-value

It quantifies the likelihood of observing the collected data if the null hypothesis were true, used in hypothesis testing as a critical component.

Null Hypothesis

A hypothesis that assumes no significant difference or effect, serving as the default assumption in statistical hypothesis testing.

Alternative Hypothesis

A hypothesis that contradicts the null hypothesis; it suggests there is an actual effect or difference.

Two-sided Test

A statistical test that considers both directions of effect by evaluating whether a parameter is either significantly higher or lower than a hypothesized value, allowing for rejection of the null hypothesis for deviations in two directions.
