Chin-Hsing conducted a study that examined motivation for sport and academics in a Taiwanese school for gifted athletes. One concern that Chin-Hsing has is that the results from the study may not generalize to another school or country. The validity threat most evident in his concern is:

a. Internal validity
b. External validity
c. Construct validity
d. Predictive validity

External validity

Explanation:

External validity is the validity of applying the findings and conclusions derived from a study outside the context of that particular study. External validity is the degree to which the results of a scientific study can be generalized to other situations and across other situations, stimuli, people, and times.

External validity helps in answering the question of whether the research carried out can be applied to the real world. When the research is applicable to other settings, people and experiments, external validity is high otherwise it is low.

Chin-Hsing study may not be generalized to other schools or country shows that its external validity is low.
