Elements of a Quasi-Design
Not a true experiment, no manipulation of an independent variable
Can approximate a group design (with no randomization of groups) or a single subject design (as a basic A-B design)
Used when resources are not available to conduct a true experiment
Can allow you to determine a hypothesis, but NOT to determine a functional relation

Elements of Group Design
True experiment
Consists of a control group and an experimental group – one gets the independent variable and the other does not
Uses inferential statistics to determine if there is a statistical difference between control group and exp. Group
^^This is how they determine a functional relation
Not often used in behavior analysis
182
Elements of Single Subject Design
