He creates two groups of 50 workers each and assigns each group the same task (in this case theyer 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 made 1587 stacks Group B made 2113 stacks. Identify the: 1. control group 2.independent variable 3.dependent variable 4. what should Smithers conclusion be? 5.how could this experiment be improved
