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… Read more
C. Measurement, Data Display, and Interpretation
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.
6th Edition TCO
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.
Measurement bias
When an observer’s measurement is influenced by an expectation or belief they hold rather than what actually occurred.
Median level line
A horizontal line on a line graph established by calculating the median of the graphed data points, used to signify the degree to which data points converge on the y-axis.
6th Edition TCO
Momentary time sampling
A time-sampling data collection method used to estimate the overall occurrence of a behavior by measuring the number of intervals during which the behavior occurs at the end of an
