Dr. Smart conducted a study in which she had students take a psychology test in a room that was very hot or in a room that was o
f a normal, comfortable temperature. Dr. Smart found that the students in the hot room performed more poorly on the test than did those students in the comfortable room. What is the independent variable in Dr. Smart's study
The independent variable is the temperature of the room
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.
