The test variable (independent variable) in this experiment is the type of cheese.

Explanation: The independent variable is the factor that is changed or controlled in an experiment to test its effects on the dependent variable. In this case, the student is varying the types of cheese to observe how this affects the amount of bacteria present, which is the dependent variable.
