Duration
Hint: Duration answers the question, “How long did that behavior last?” A measurable dimension of the amount of time that a behavior persists from onset (i.e., the start) of the… Read more

Equal interval graph
A graph, used to analyze the effects of treatment on a target behavior over time, that visually represents data in which the distance between any two consecutive points on the
Indirect measures of behavior
A measurement of behavior that is not based on an actual observation of the behavior itself, but a secondhand account of the behavior’s occurrence (e.g., rating scales, permanent product, descriptive
Interobserver agreement (IOA)
A measurement of the degree to which two or more observers report the same values when observing and collecting data for the same behaviors/events.
Interresponse time (IRT)
A measurable duration of time that elapses between two consecutive instances of a response.
Latency
The measurable duration of time between the onset or appearance of a stimulus and the initiation of the response.
Level
On a line graph, the degree to which the data points on the y-axis converge, established by calculating the mean or median of the graphed data points.
6th Edition TCO
Line graph
A chart used to display the occurrence of behavior across specific time periods. Each data point shows the level of some quantifiable feature of the dependent variable in relation to
Magnitude
The measurable dimension of a behavior’s strength, force, intensity, and/or severity.
6th Edition TCO
Mean level line
A horizontal line on a line graph established by calculating the average of the graphed data points; used to signify the degree to which data points converge on the y-axis.

Measurement artifact
Data that represents an unwarranted and misleading picture of behavior because of how it was measured, typically a product of time-sampling, limiting measurement scales, or poorly scheduled measurement periods.
