The five basic characteristics referenced in the chapter. 1. The experimenter establishes two groups: an experimental group (there can be more than one) that receives or is exposed to an experimental treatment, or test stimulus or factor; and a control group, so named because its subjects do not undergo the experimental manipulation. 2. Equally important, the researcher randomly assigns individuals to the groups. The subjects do not get to decide which group they join. The random assignment to groups is called randomization, and it means that membership is a matter of chance, not self-selection. 3. The researcher controls the administration or introduction of the experimental treatment (the test factor)—that is, the researcher can determine when, where, and under what circumstances the experimental group is exposed to the stimulus. 4. In an experiment, the researcher establishes and measures a dependent variable—the response of interest—both before and after the stimulus is given. The measurements are often called pre- and post-experimental measures, and they indicate whether or not there has been an experimental effect. An experimental effect, as the term suggests, reflects differences between the two groups’ responses to the test factor. 5. The environment of the experiment—that is, the time, location, and other physical aspects—is under the experimenter’s direction. Such control means that he or she can control or exclude extraneous factors, or influences, besides the independent variable that might affect the dependent variable. If, for instance, both groups are studied at the same time of day, any differences between the control and experimental subjects cannot be attributed to temporal factors.
