Chapter Seven Flashcards
Control
Any means used to rule out threats to validity.
Experimental Group
Subjects in an experiment that receive treatment.
Control Group
Subjects in a in between subjects design experiment who are identical to the experimental group except that they do not receive treatment.
Control Condition
A condition in a within subjects design experiment that does not contain the experimental manipulation.
Within-Subjects experiment
Research design in which each subject experiences every condition of the experiment.
Between Subjects Experiment
Research design in which the subjects experience only one of the conditions in the experiment.
Random Assignment
Unbiased assignment process that gives each participant an equal and independent chance of being placed in every condition.
Matching
Control procedure to ensure that experimental and control groups are equated on one or more variables before the experiment.
Nuisance Variable
A condition in an experiment that cannot easily be removed and so it is made into an independent variable as a means of control.
Statistical Control
Mathematical means of comparing subjects on paper when they cannot be equated if they exist in fact.
Replication
Repeating an experiment to see if the results are the same.
