Impact of Monetary Incentives on Math Performance in Middle School Students
Analysis of the Experiment
Independent Variable: The $5 monetary incentive offered to half of the middle school students acts as the independent variable in this experiment. It is the factor that is manipulated by the researchers to observe its effect on the students' performance on the math test.
Dependent Variable: The test performance of each student is the dependent variable in this experiment. It is the outcome that is measured to determine whether the monetary incentive had any impact on the students' abilities in math.
Experimental Group: The students who were offered $5 for achieving a certain level of performance on the math test make up the experimental group. This group is the one that receives the treatment being studied, which in this case is the monetary incentive.
Control Group: The students who were not offered any money to take the math test form the control group. This group provides a baseline for comparison to see if there is a difference in performance between those who received the incentive and those who did not.
