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.
