Final answer:
External validity is the type of validity used to assess if study results can be generalized beyond the specific sample used in the research.
Step-by-step explanation:
The type of validity used to determine if the results generalize beyond the sample is external validity. External validity refers to the extent to which the findings of a study can be generalized to other settings, populations, and times. It's about the applicability of the study's conclusions outside of the controlled conditions of the research.
Internal validity is concerned with the rigor with which the study was conducted and if the results obtained are solely due to the variables tested. Construct validity relates to how well a test or tool measures the concept it's intended to measure. Content validity assesses whether a test or tool fully captures the entire range of a concept.
