The experimental group gets the experimental manipulation—that is, the treatment or variable being tested (in this case, violent TV images)—and the control group does not. An experimental group is a group in which members of the groups are exposed to independent variable manipulation. Control Condition (control group) During many experiments, researchers often include treatment groups (the groups that are given the treatment/IV) and a control group, which is identical to the treatment group in every single way except that the control group does not get the treatment/IV. Set of tested hypotheses that gives an overall explanation. Example: In the study by Latane and Darley, there were two experimental groups and one control group. Some experiments might only have one experimental group while others may have several treatment variations. Researchers change the independent variable in the treatment group and keep it constant in the control group. A control group is used in an experiment to establish its validity. For example, if researchers were to design an experimental study to test the effect of loud music on test performance, students who did not listen to loud music would be in the control group. For example, imagine a study of a new drug in which all of the female participants were assigned to the experimental group and all of … The control group is the group in an experiment that does not receive the variable you are testing. In this case, the control group ensures that no confounding variable or bias has affected the results. . The control group is used as a part of the process that assesses the validity of your results. This insures that the effects of the variable are being studied. A total of 300 participants are randomly assigned to the primary experiment, the negative control group and the positive control group such that each group … This can best be described using an example. Imagine, for example, a researcher who is interested in the effectiveness of an anti-drug education program on elementary school students’ attitudes toward illegal drugs. One way would be to conduct a study with a treatment group consisting of one class of third-grade students and a control group consisting of another class of third-grade students. Test. In order to avoid experimental bias, experimental blinds are usually applied in between-group designs. Revised on August 3, 2020.
