If we give half the patients a placebo, then what do you give the control group?
In: 0
Nothing.
So, you tell your subjects that you are testing a new allergy med. You seperate them into three groups.
Group 1 gets a proven allergy med
Group 2 gets a sugar pill
Group 3 is the control and gets nothing
If the placebo affect is real, group 2’s results should fall somewhere between 1 and 3.
