A control group is usually used in experimental psychology to study the effect of an intervention or treatment. Research in psychology covers a number of topics. Sometimes, in order to verify whether an effect is significant, it is necessary to compare two groups or more. One of these groups will be a control group. A control group will often present the same characteristics as the other groups but will not be exposed to treatment or intervention, contrary to its counterpart(s). For example, group A can receive a newly developed therapy for depression, whereas the control group will not receive this therapy. Later on, both depressed groups will be compared to determine if the therapy had a significant effect, or, in other words, if it worked. Another example pertains to social therapy. A researcher could study the effect of setting short terms realistic goals on attaining long term goals. As such, a group of students would receive help on how to set short term goals, how to reach them, how to deal with obstacles, etc to attain long term goals. The control group, also made of students, would not receive such an intervention and would be told to set up long term goals and try to achieve them. At the end of the research period, both groups would be compared to see whether the intervention in helping setting short term goals and achieving them made a difference in term of goal achievement.

∙ 11y agoAt least two subjects are necessary, an experimental group, for whom the independent variable changes in the prescribed manner, and the control group for whom it does not. The subject of both these groups are chosen that are nearly as possible identical. finally the results of both groups are compared with one another.

∙ 13y agoThe control group remains the same at the beginning and end of an experiment. On the other hand, the experimental group has one or more variable manipulated to see the effects. For example: consider testing the effects of seat belts in cars. The control group would be the one without a seat belt. The experimental group is the one with a seat belt, thus showing the effects of a seat belt.

the logic behind group matching is to ensure that experimental and control group are equvilant on some criterions( sex, race, height etc).

Are control groups and experimental groups the same thing?
In a controlled experiment, there are two groups. The control group is a group that nothing happens to. The experimental group is the group that you subject to the variable with which you are experimenting. At the end of the experiment, you test the differences between the control group, for whom nothing happened, and the experimental group, which received the variable. The difference (or similarities) between the two groups is how your results are measured.A control group is the group used for comparison in an experiment. One group receives the treatment that is being tested by the experiment; another group (the control group) has the exact same controlled environment, but does not receive this treatment. The effectiveness of the treatment can then be established by comparison with the control group.
