Document Summary

Advantage: shows level of behaviour before treatment and after treatment. A vertical line that indicates a change in treatment. Data points here are no connected to show differences in level of behaviour in different phases. The treatment phase should identify the treatment type. All 6 components should be included each time a graph is drawn! Purpose of research design: to determine whether the independent variable caused a change in the dependent variable. The independent variable is the variable the researcher manipulates. The dependent variable is the variable that changes as a result of the independent variable. A confounding variable is any factors that can influence the dependent variable. A functional relationship is demonstrated when a. b. The target behaviour changes as a result of the behaviour modification procedure used. The b-mod procedure is repeated several times and, the behaviour changes each time. A type of design where there are only 2 phases baseline (a) and treatment (b)
