Question

Quizplus · Accepted Answer

The dependent variable is the variable being measured or tested in the experiment. In this case, the test performance is the variable being measured and compared between the two groups of students. The independent variable would be the variable that is being manipulated, which is the location where the students studied. The manipulation refers to the act of changing the independent variable to observe its effects on the dependent variable. A control group refers to a group that is not exposed to the independent variable, which is not applicable in this experiment.
