The dependent variable is the variable being measured or tested in the study, which in this case is the students' performance on the exam. The independent variable is the variable being manipulated or controlled, which is whether or not the students receive the study guide. In this study, the study guide is the independent variable. Group 1 receiving the study guide and Group 2 not receiving the study guide are just different levels of the independent variable.
