Graphing Behavior and Measuring Change
β’Primary tool used to document behavior change is a graph β a visual
representation of the occurrence of a behavior over time
β’Graph is efficient because it shows the results of recording during
many observation periods
β’Use graphs to identify the level of behavior before treatment and after
treatment begins
β’The long period after treatment has been implemented is called the
follow-up period
Components of a Graph
β’In a typical graph, time and behavior are the two variables
β’Each point gives you the time of the behavior and the level at that time
β’Time β horizontal axis (x-axis/abscissa)
β’Level of behavior β vertical axis (y-axis/ordinate)
β’6 components are necessary for the graph to be complete:
oThe y-axis and x-axis
ξX and y meet at the bottom left of the page
ξX-axis usually longer than y-axis (1-2 times as long)
oThe labels for the y-axis and x-axis
ξY-axis tells you the behavior and the dimension of
behavior that is recorded
ξX-axis tells you the unit of time during which the
behavior is recorded
oThe numbers on the y-axis and the x-axis
ξOn the y-axis, the numbers indicate the units of
measurement of the behavior
ξOn the x-axis, the numbers indicate the units of
measurement of time
ξThere should be a harsh mark on both axisβs to
correspond to each of the numbers
oData points
ξInformation taken from data sheet or other behavior
recording instrument
ξEach point is connected to the adjacent point by a line
oPhase lines
ξA vertical line on a graph that indicates a change in
treatment

## Document Summary

x and y meet at the bottom left of the page. x-axis usually longer than y-axis (1-2 times as long: the labels for the y-axis and x-axis. y-axis tells you the behavior and the dimension of behavior that is recorded. x-axis tells you the unit of time during which the behavior is recorded: the numbers on the y-axis and the x-axis. on the y-axis, the numbers indicate the units of measurement of the behavior. on the x-axis, the numbers indicate the units of measurement of time. there should be a harsh mark on both axis"s to correspond to each of the numbers: data points. Information taken from data sheet or other behavior recording instrument. each point is connected to the adjacent point by a line: phase lines. a vertical line on a graph that indicates a change in treatment www. notesolution. com.
