The independent variable in this study is the location where students study, as this is the variable that is being manipulated by the researcher. The dependent variable is the test performance of the students, which is measured to determine whether there is a difference between the two groups. The manipulation is the assignment of students to either the classroom or library to study. The hypothesis is the statement being tested, which in this case is that studying in the same room as the test will lead to better performance.
