You are correct, the independent variable in this experiment is the amount of money offered. The independent variable is the variable that is intentionally manipulated or changed by the researcher in order to assess its effect on the dependent variable, which is the variable being measured or observed. In this case, the science teacher wants to see if offering money for good grades will affect student performance on the test, so the teacher manipulates the independent variable by offering money to only half of the students in the class and not offering money to the other half. By comparing the performance of the two groups, the teacher can see if the independent variable (the amount of money offered) has any effect on the dependent variable (student performance on the test).
