What do control groups control?

Control groups are non-experimental groups -- that is,
they have not been subjected to the experimental treatment. For
example, if you are testing a new drug, the experimental
group (also called the "treatment group") gets the drug, and
the control group does not.
Control groups are necessary in order to show that the treatment
causes an effect. If the experimental group shows changes, but the
control group does not, then it is possible that those changes were
caused by the treatment. If there is no control group, then there
is nothing to compare the experimental group to.
Additionally, a control group is usually given an equivalent
treatment. In the drug study, the control group would receive a
placebo, such as a sugar pill. In such cases, control groups
may be called placebo groups. This is done in order to show
that any observed effects are caused by the treatment itself, and
not by the process of administering treatment. In this way, we are
controlling for the placebo effect -- a
psychologically-induced response to a fake treatment, in which
people begin to get well because they think they should be
getting well.
