Quizplus · Accepted Answer

The dependent variable in this study is the performance of each student on the exam, as it is the outcome being measured and is expected to change based on whether or not the students received the study guide. The study guide (A) and the group that did not receive the study guide (B) are independent variables, as they are being manipulated by the researcher. There is always a dependent variable in a study, as this is the variable being measured and analyzed to draw conclusions. Therefore, D is not a correct answer.
