Graphing Behavior and Measuring Change
Primary tool used to document behavior change is a graph a visual
representation of the occurrence of a behavior over time
Graph is efficient because it shows the results of recording during
many observation periods
Use graphs to identify the level of behavior before treatment and after
treatment begins
The long period after treatment has been implemented is called the
follow-up period
Components of a Graph
In a typical graph, time and behavior are the two variables
Each point gives you the time of the behavior and the level at that time
Time horizontal axis (x-axis/abscissa)
Level of behavior vertical axis (y-axis/ordinate)
6 components are necessary for the graph to be complete:
oThe y-axis and x-axis
X and y meet at the bottom left of the page
X-axis usually longer than y-axis (1-2 times as long)
oThe 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
oThe 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
oData points
Information taken from data sheet or other behavior
recording instrument
Each point is connected to the adjacent point by a line
oPhase lines
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.
