QUESTION:

In an experiment to see the effects of alcoholic beverages on behavior, a placebo is:

the place where the subjects go when they have to sleep off the effects of alcohol.

non-alcoholic beer that looks and tastes just like regular beer but contains no alcohol.

a procedure for deciding who gets regular beer.

the sampling method.

the randomization procedure.

ANSWER:

non-alcoholic beer that looks and tastes just like regular beer but contains no alcohol.

A placebo is a non-active treatment used in a study for proper comparison. In this case, it ensures that any comparative effect in the alcohol group is really due to the active ingredient, rather than the "placebo effect."
