Deandre is new teacher at a local elementary school. He decides to conduct a brief study testing the fifth graders knowledge of science at the beginning of the school year and at the end of the school year. He will randomly assign students to either a "hands-on" science group that does experiments with each lesson plan or to a "video" science group that assigns videos and online tutorials in support of the science lesson plans. Based on this information which of the following would be considered the dependent variable (DV)?

Question

Quizplus · Accepted Answer

The dependent variable (DV) is the variable that is being measured or tested in an experiment. In this study, the pretest and posttest of science knowledge is the variable that is being measured and compared between the "hands-on" and "video" science groups. Therefore, the correct answer is B. A is the independent variable (IV) because Deandre is manipulating it by assigning students to different science groups. C and D are not relevant variables in this study.
