Definitions:

Significance Level

A rephrased version for Level of Significance; it's the probability of rejecting the null hypothesis when it is true, serving as a critical threshold for determining the statistical significance of an observed effect.

Critical Value

A point on the scale of the test statistic beyond which we reject the null hypothesis; it is the cutoff point that determines the boundary of the rejection region for a statistical hypothesis test.

Adjusted Coefficient

A statistical measure modified to account for various factors or variables, improving its accuracy or relevance.

Partial-regression Coefficient
