Here we examine what the experimenter is measuring in relation to the manipulated condition.
Option 1: confounding variable. A confound would be an unintended variable that varies with the manipulation and could influence aggression, making it unclear whether temperature or the confound caused any change. This is not what aggression is in this setup, though confounds are a concern in experiments.
Option 2: independent variable. The independent variable is the factor deliberately changed by the researcher to observe its effect. In this scenario, room temperature is what the experimenter changes, so temperature is the independent variable, not aggression.
Option 3: control variable. A control variable is something kept constant to prevent it from influencing the outcome. While temperature experiments often require controlling other factors, aggression itself is not the variable being held constant; the researcher is intentionally varying the temperature, not keeping it fixed.
Option 4: dependent variable. The dependent variable is what is measured to assess the effect of the manipulation. Since aggression is the behavior measured to see how it changes with different room temperatures, aggression is the dependent variable.
