The independent variable is the variable that is manipulated by the researcher, in this case, the type of music played. The dependent variable is the variable being measured, which in this case is the students' test performance. The intervening variable is a variable that may impact the relationship between the independent and dependent variables, but is not directly manipulated by the researcher in this case. The criterion variable is a variable used to evaluate the effectiveness of a treatment or intervention, but it is not applicable in this study as no treatment or intervention was given.
