The independent variable is the variable that is being manipulated by the researcher in order to observe its effect on the dependent variable. In this case, the researcher is manipulating the color of the room, so room color is the independent variable. Blood pressure is the dependent variable, as it is expected to vary based on the color of the room. Anxiety level is not the independent variable, as it is not being directly manipulated; rather, it is a potential mediator or confounding variable that may be affected by or affect the independent variable. Building type is not mentioned in this scenario and is therefore not a variable in this study.
