Practice with Defining Variables
Example Experiment 1:
Smithers believes that his workers at the factory could be more productive. He
thinks that a special juice will increase the productivity of workers. He selects
two groups of 50 workers each and assigns each group the same task (in this
case, they're supposed to staple a set of papers). Group A is given a special
juice to drink while they work. Group B is not given the special juice. After an
hour, Smithers counts how many stacks of paper each group has made. Group
A made 6,587 stacks, Group B made 1,113 stacks.
