The Answer is Independent variable: This is the variable that experimenters manipulate.
Dependent variable: This is the variable that experimenters use as an outcome.
Moderating variable: This is a variable that influences the relationship between the independent and dependent variables.
Example: School interventions were manipulated and student performance was measured as an outcome. A mediating variable could be parental involvement such that parents who were more involved led students to benefit more from the intervention. Student who have non-involved parents may show performance that do not statistically differ between the two experimental conditions. Thus, parental involvement moderates the relationship that this intervention has on the outcome variable.
