Question

Suppose that you want to test the effects of different dishwashing detergents on dishes that have food stuck to them. To test the differences, you wash three loads of the same dishes, each with a different type of detergent, all in warm water. You also wash a fourth load of dishes with only warm water. What is the control in this experiment?

PLEASE HELP MEE

Answer 1

the controlled variable is the variable that remains the same throughout the whole experiment. Here, the warm water and the same dishes are the same throughout the whole experiment- so they are the controls
