Review of Key Terms

Dependent Variable—The variable in a study that is measured by the researcher.
Description—Carefully observing behavior in order to describe it.
Experimental Group—The group of participants that receives some level of the independent variable.
Experimental Method—A research method that allows a researcher to establish a cause-and-effect
relationship through manipulation of a variable and control of the situation.
Explanation—Identifying the causes that determine when and why a behavior occurs.
Hypothesis—A prediction regarding the outcome of a study, often involving the relationship between
two variables in a study.
Independent Variable—The variable in a study that is manipulated by the researcher.
Knowledge via Authority—Knowledge gained from those viewed as authority figures.
Knowledge via Empiricism—Knowledge gained through observation of organisms and events in the
real world.
Knowledge via Intuition—Knowledge gained without being consciously aware of its source.
Knowledge via Rationalism—Knowledge gained through logical reasoning.
Knowledge via Science—Knowledge gained through a combination of empirical methods and logical
reasoning.
Knowledge via Superstition—Knowledge that is based on subjective feelings, belief in chance, or belief

Survey Method—Questioning individuals on a topic or topics and then describing their responses.
Systematic Empiricism—Making observations in a systematic manner in order to test hypotheses and
refute or develop a theory.
Theory—An organized system of assumptions and principles that attempts to explain certain phenomena
and how they are related.
