Definitions:

Independent Variable

A variable that is manipulated or changed in an experiment to determine its effect on the dependent variable.

Room Temperature

A general description of a comfortable indoor environment, typically considered to be around 20°C (68°F) to 22°C (72°F).

Noise Level

The measurement of the ambient level of sound, often referring to the background sound present in a given environment.

Internal Validity

The degree to which a study’s results are attributable to the independent variable, rather than other factors, indicating the study accurately reflects the relationship being tested.
