An environmental psychologist conducted an investigation into the relationship between the ambient room temperature during an intensive training session and the subsequent levels of mental fatigue reported by participants. The researcher utilized a correlational design with a sample of 30 corporate employees.
During the session, the room temperature (in ∘C^\circ\text{C}∘C) was continuously monitored. Following the session, each employee completed a 15-item mental fatigue questionnaire, yielding a score between 15 and 75.
