Dr. Wilson who teaches engineering classes is interested in learning about how lack of sleep affects Performance. What would be the best way to ensure That her findings are generalizable so all the students at her university

He should do a scientific experiment with volunteers who are students of different courses.

Explanation:

In order for Dr. Wilson's research results to be generalizable across the university, he must provide results that show examples in the most diverse fields that the university covers. This will be simple to establish, if he, when looking for volunteers from his research, instead of concentrating the demand in a single sector of the university, focus on the search for volunteers in all sectors, thus reaching students from the most varied courses, present in institution.
