Final answer:
The term that describes how well an experiment's findings generalize to an entire population is called external validity.
Step-by-step explanation:
The term that describes how well an experiment's findings generalize to an entire population is called external validity.
External validity refers to the ability to generalize the results of a study to a larger population beyond the individuals who participated in the study.
It is important to ensure that the sample used in the experiment is representative of the entire population in order to make valid generalizations.
