Quizplus · Accepted Answer

The independent variable is the variable that is being manipulated or controlled by the researcher. In this case, the independent variable is the room color, as the researcher is purposely assigning patients to rooms with different colors. The blood pressure and anxiety level are dependent variables, as they are measured and expected to change based on the independent variable. Building type is not relevant to the study and is not mentioned as a variable.
