Answer:
Non experimental - field.
Explanation:
An IO psychologist (Industrial-organizational psychologist) aims to use psychological principles and research methods to solve problems and improve the quality of life. As Chaubroeck and Kuehn found, many of the studies made by I-O psychologists were not experimental and took place in field settings, therefore, they are more a personal or individual experience rather than facts. They found that 67 percent of the studies were made in field settings and only 33 made in laboratories, with students as participants.
