It is the variable the researcher manipulates in the experiment.
Define: a Dependent Variable
is the variable that is thought to be affected by the manipulations of the independent variable”.
It is usually a measurement of behavior.
Define: the Experimental Group
consists of the subjects who receive some special treatment in regard to the independent variable”.
In Schachter’s (1959) study, the experimental group was told the shocks would be painful.
Define: the Control Group
consists of similar subjects who do not receive the special treatment given to the experimental group”.
What is the advantage of using experiments?
precise control allows cause and effect conclusions to be drawn.
What is the disadvantage of using experiments?
there are some variables of interest that cannot, for ethical reasons, be manipulated in an experiment.
Correlational Research is
Looking for links
A correlation exists when?
two variables are related to each other
Define: A correlation coefficient
