Definitions:

Two-tailed Hypothesis

A hypothesis test that considers both directions of an effect, allowing for the possibility of difference in either direction from the null hypothesis.

Critical Values

Specific points on the scale of a test statistic beyond which we reject the null hypothesis, crucial in hypothesis testing to determine the significance of the results.

Critical Value

A threshold in a statistical test that defines the boundary for rejecting the null hypothesis.

Critical Value

A threshold value used in hypothesis testing that defines the boundary between the region where the null hypothesis is rejected and the region where it is not rejected.
