Help with control group and variables?

Bob thinks that a special drink will increase the productivity of his workers. He creates two groups of 50 workers and assigns each group the same task. Group A is given the special drink while they work, and Group B isn't given the special drink at all.


What are the control group, independent variable, and dependent variables in this case?


can someone explain how to find them please?Help with control group and variables?
The Control Group are the workers without the special drink so Group A





The Independent Variable is the special drink





and the dependent variable is the workers





(i'm pretty sure that's right)
