Suppose a scientist wants to test a new drug to fight the flu. The scientist injects the drug into three people with the flu. The scientist injects a harmless solution into three other people with the flu.|||The variable group is the drug.
The control is the people who get the harmless solution.|||Think of the harmless drug like a placebo, if that makes it easier... He is administering the drug this way so he can see whether or not the drug has any affect on the flu patients. Think of what he is changing in order to test the drug (the variable) and what he is holding constant; that should give you your answer...|||The control group is the harmless solution, and the variable group is the flu group.
