Smithers thinks that a special juice will increase the productivity of workers. He creates two groups of 50 workers each and assigns each group the same task (in this case they are supposed to staple a set of papers). Group A is given the special juice to drink while they work. Group B is not given the special juice. After an hour Smithers counts how many stacks of papers each group has made. Group A make 1,587 stacks Group B made 2,113 stacks. Identify the control group, independent variable, dependent variable, what should smithers conclusion be and how could this experiment be improved
