Definitions:

P-value

A statistical measure that helps to determine the significance of results obtained in hypothesis testing.

Observed Value

The actual data point or result that is measured or collected in an experiment or study.

Dependent Populations

Populations in which the members or subjects are not independent of each other, meaning the selection or outcome of one influences another.

One-tailed Test

A hypothesis test where the region of rejection is on only one side of the sampling distribution.
