The independent variable is the variable that is manipulated by the researcher to see its effects on the dependent variable. In this case, the independent variable is the number of breaks taken - whether it's one 45-minute break or three 15-minute breaks. The dependent variable is the memory for the material. The topic being studied and the professor's lecture time are not manipulated by the researcher and are not independent variables.
