Question

Quizplus · Accepted Answer

By controlling sounds, smells, and temperature in a testing environment, a researcher aims to reduce situation noise. Situation noise refers to any extraneous variable that could impact the results of the study, which includes environmental factors such as background noise, odors, and temperature. By reducing situation noise, a researcher can increase the internal validity of their study by ensuring that any observed effects are due to the manipulated variables and not to any confounding factors.
