Explanation:
In every experiment, there are two kinds of variables; the dependent variable and the independent variable.
The independent variable is the variable that is manipulated and its impact on the dependent variable is observed. Hence the dependent variable is that variable that changes in response to changes in the independent variable.
In this study, the performance of students was found to change as the temperature of the room changes. Hence the temperature of the room is the independent variable while the performance of the students is the dependent variable.
