Chapter 8. Experiments
Introduction
 In experiments, social researchers typically select a group of subjects, do something to them, and observe the effect of what was done.

Topic Appropriate to Experiments
 Experiments are an excellent vehicle for the controlled testing of casual processes.

The Classical Experiment
 The classical experiment tests the effect of an experimental stimulus (the independent variable) on a dependent variable through the pretesting and post testing of experimental and control groups.

 It is generally less important that a group of experimental subjects be representative of some larger population than that experimental and control groups be similar to each other.

 A double-blind experiment guards against experimenter bias, because neither the experimenter nor the subject knows which subjects are in the control and experimental groups.

Selecting Subjects
 Probability sampling, randomization, and matching are all methods of achieving comparability in the experimental and control groups. Randomization is the generally preferred method. In some designs, it can be combined with matching.
