Definitions:

Null Hypothesis

A statistical hypothesis that suggests there is no significant difference between specified populations or no effect.

P-Value

A statistical measure that helps to determine the significance of the results obtained from a test, indicating the probability of observing the results given that the null hypothesis is true.

Level Of Significance

A threshold in hypothesis testing that determines the probability of rejecting the null hypothesis when it is actually true; commonly denoted by alpha (α).

Multicollinearity

A statistical phenomenon in which two or more predictor variables in a multiple regression model are highly correlated, potentially affecting the reliability of the model's estimates.
