3 Graphing Behaviour and Measuring Change The primary tool used to document behaviour change is the graph Recorded information is transferred to a graph Efficient way to view the occurrence of the behaviour because it shows the results of recordings during many observation periods Used to identify the level of behaviour before and after treatment The long period after treatment on the graph, is called the follow-up period Components of a Graph Time and behaviour are the two variables (when the behaviour was recorded, and the level of the behaviour at that time) Time is indicated on the horizontal axis (abscissa), level of behaviour is indicated on the vertical axis (ordinate) Six components are needed for a graph 1. The y-axis and x-axis (usually longer by one to two times) 2. The labels for the y-axis and x-axis 3. The numbers of the y-axis and x-axis 4. Data points 5. Phase lines: a vertical line on a graph that indicates a change in treatment, such as from a no- treatment phase to a treatment phase, or vice versa Data points are not connected across phase lines Allows you to see differences in the level of the behaviour in different phases more easily 6. Phase labels: appears at the top of the graph above the particular phase Have at least two phases that are labelled the no-treatment phase and the treatment phase www.notesolution.com
