Researchers conduct an experiment in which one group is exposed to treatment a and the other group is exposed to treatment b. if the group exposed to treatment a is designated as the treatment group, the group exposed to treatment b is the:

The answer to the question: If the group exposed to Treatment A is designated as the treatment group, the group exposed to Treatment B is the:, would be: Control group.

Explanation:

In experimental research, the purpose is to expose subjects to certain situations, or characteristics (an event, but most usually treatments), to ascertain the effectiveness of one treatment over another, or, establish if the treatment produces more, or less, positive effects, than when there is no treatment at all. In one word, the idea is to compare. In order to do that, there are several conditions that must be met, and one of them is the independent variable, in this case, the treatments. However, in order to compare, a group of subjects must be selected, and these must be assigned into groups. The first group is known as the experimental group, because they will receive the actual treatment, which is treatment A, and the other group, is known as a control group, they will also receive treatment, known as Treatment B, but this one will most likely be a placebo, or an actual treatment which they want to compare, which means, it will have no effect. This will help researchers determine if Treatment A, or Treatment B, are more effective.
