Question
In its simplest form, an experiment has three essential characteristics. Of the following, the one which is not a characteristic of experiment is _________ A. an experimental manipulation of the independent variable B. an experimental manipulation of the dependent variable C. a measurement of the dependent variable D. attempts to control for extraneous factors.
Solution
The characteristic that is not a part of an experiment is B. an experimental manipulation of the dependent variable. In an experiment, the independent variable is the one that is manipulated or changed by the researchers, while the dependent variable is the one that is measured to see how it is affected by those changes. The dependent variable is not manipulated by the researchers.
